With Flash player 8.0 this Web 2.0 app runs like charm, a flash based website to access Google Talk (Gtalk), Gtalkr launched yesterday.Gtalkr is a web-based IM client that communicates with the Google Talk service.
It is currently in Beta stage. Few features I would like to mention is the Yahoo! Maps integration into it, desktop integration and ability to add their own extensions for flash developers.

Instant messaging is almost as popular as email, so why is it that you can’t search your conversations from within your IM client? Gtalkr automatically stores and indexes all your conversations, providing the same great searching you’ve come to expect from email.
