My favorite directory of Web 2.0 sites, Go2Web20, received a much needed interface upgrade. Go2Web20 is a flash site that had a sleek, but slow and relatively buggy interface, from which you could get information on new Web 2.0 sites and services.

In the new interface, one notoriously annoying bug is fixed: now when you click on the website address of some company, it actually opens right away (before, you had to click 2-5 times) in Firefox.

There a still a couple of minor quirks. For example, in Firefox, mouseovering over a company logo sometimes makes the cursor rapidly change between the click me and you can’t click me state. Overall, though, the interface works much better than before, and I recommend every Web 2.0 enthusiast to check it out.

Also, the site is now open to advertisers. You can check the details here.

If the site doesn’t work for you, don’t be alarmed. Currently, the Go2Web20 is experiencing some problems due to a DNS change, but the owners expect everything to be running OK very soon.
