I just started to test the combination of Jetbrains Omea Reader and IMHO 1.0 Instant Blogger. Omea is good when you read rss feeds and newsgroup. I like the way you can search, create categories, views… For the moment I couldn’t find an easy way to quickly se the thread I started or replied to for examples in all my newsgroups.
Concerning IMHO, it is my first post, so I will see after some time, but I really like it’s simplicity.
