I installed it, I started it, and in 5 seconds I was watching television.
I did it for an hour before I remembered that I’m actually supposed to review the thing. I guess there’s no greater praise, but for those who like details, I’ve included the details as well. So, here’s what I think about Joost, the latest project from the authors of Skype, formerly dubbed as the Venice Project, for whose beta I was lucky to be invited a couple of days ago.
Introduction and installation
Joost is a streaming P2P platform for television. It brings you TV or near-TV quality content in an application that uses P2P protocols to fetch the content, but it’s not really transparent to the user, who simply has to start using it and needs not worry about how it does its thing. The app is based on Mozilla’s XULRunner engine, which basically means it’s cross-platform. It’s ad-funded, and from what I understand you won’t be able to simply share content on Joost like you can on YouTube. It’s TV in the old fashioned sense of the word - they give you content, you watch it; only on internet. It makes up for this with the quality of the content and the features of the software.
The installation is simple and smooth. Joost was behaving very nicely and it never crashed or stopped responding. I’ve noticed that when playing a video, Joost, on average, eats up around 35% of CPU time which is not that bad, but it’s also not negligible, as my Opteron 144 overclocked to 2.8 GHz is a relatively speedy beast.
GUI
Joost starts in full screen. Unaccustomed to this kind of behaviour, I was startled for a few seconds before I remembered that this is nothing like YouTube or BitTorrent. It’s television. The general idea is that you fire it up and start watching, and in this Joost succeeds immensely.

In accordance to this, the GUI looks more like a media center interface than your standard Windows application. The icons are big and easy to hit, and while the scrolling may be a little slow at some points, it’s perfect for using on the TV screen. The GUI consists of the main controls at the bottom, channel chooser on the left, info link on top and a link to My Joost, your customized Joost screen where you can load up plugins, on the right. A button for making the menu items invisible is on top left, and double click switches between full screen mode and window mode (in window mode Joost looks like a detached window of a media player such as BSplayer). It’s not the most beautiful GUI design I’ve seen but it’s good enough, and what’s more important, all of it’s transparent and made with the idea of not getting in the way of your viewing experience.
Video quality and content
I’ve got a 100 KB download connection - definitely not the fastest in the world - and the videos did stutter, but rarely. This was my biggest concern, and I can say that Joost passed this test, although not with a perfect grade - I expect further improvements in this department in the future. The actual quality of the videos varied quite a bit, but it was definitely much better than anything on YouTube or Google Video. Overally, I’d call it a compromise: it’s just barely good enough for full screen, but not any better than that. This said, the quality probably improves with the speed of your connection. Still, it’s beautiful to switch to this after all those low quality videos I’ve been seeing on the internet for years. A revolution? Maybe. I can’t stop watching it, that’s for sure.

One thing I cannot judge well at this point is the amount or variety of content the service will ultimately have. Currently, there’s enough content to watch, however there’s not nearly enough content to do a search and actually get meaningful results. The amount of content will grow when Joost goes out of beta invite-only mode, and some big fishes might jump in (currently you can, for example, watch content from MTV, or the famous auto show Fifth Gear) but what I’d actually like to see on it is cheap, independent productions. I hope they introduce a model for people to get their own content up there, because it would bridge the gap between old school TV and YouTube, but I don’t know if this will ever happen.
Plugins

One of the most important features of Joost is the support for plugins. If you’re looking at Joost as a competitor to YouTube, all that was said so far makes it clear that it definitely has some advantages (and many differences). However, if you look at it as a competitor to television - be it television from a TV tuner, cable TV or IPTV, then plugins are what’s going to make the difference. Joost’s plugins are simply widgets you can load in your Joost screen, and currently these include clock, feed reader, instant messaging (Jabber and Google talk are currently supported), rating plugin which enables you to rate the current clip with grades from 1 to 5, notice board, and channel chat. This is not bad at all, but the developers are promising many more to come. The widgets are somewhat basic but fully functional, however it’s not really important, as the possibilities are huge. Imagine watching television and chatting about it on the TV screen itself. Or watching a concert and reading new posts from your favorite sites. In one word, it’s great.
What’s not to like?

Ads. I’ve seen commercials break the program in half without a warning, which is annoying and I hope it’s just a glitch and not a ‘feature’. Other than that, ads are what Joost is funded upon and we can definitely expect them - I just hope they don’t get overly intrusive. I also expect more content and a better way to organize your own content, opposed to the current simple My Channels list. I could add other minor points, but I expect that a lot of things that are missing that I could name will probably happen in the way of a plugin.
Conclusion
Well, it’s free TV. It can’t be bad. The application works great, looks ok, and if you got a decent internet connection, you’ll have no problems using it. Its success will depend on the amount and quality of content, and of course, ultimately, the success of Joost’s ad-based business model. Everything else seems to be in place, so if the content is there, I’m sure people will love it.
*the test platform was Windows XP SP2, Opteron 144, 1 GB DDR RAM, DFI UT NF4 SLI-D Nforce4 motherboard, and a 100 KB/s download on an ADSL connection. The tested version of Joost was 0.7.3.1
