ThinkFree is one of the many AJAX built application suites that are released these days. ThinkFree offers a 'full' office replacement : One is able to create word documents (.doc), Excel spreadsheets and Powerpoint presentations online, without having any installed software besides a browser. The creaters claim full compatibility with Microsoft Office. The suite also features an option to post to your weblog - it supports almost all blog API's out there. When you login, one of the first things I noticed are three big buttons for the office documents mentioned before. Te suite looks pretty straight forward, although it took me a while to understand how to post to my blog - you have to do it by creating a document first. I think it's a nice initiative, but it definitely needs improvement. ThinkFree is currently Alfa software.
