I also am a huge fan of the event feed implementation. I'm also very disappointed with the stock twitter client and I think Tweetian is a must have for anyone who uses twitter.

I think the reason why I like the event feed so much is that I mostly just read tweets, I rarely tweet or retweet anything. This is why I still have the stock client fill the event screen. I use Tweetian when I need streaming or just want to zoom in on a picture. It is also generally sooo much better to use when in app. I would very much like to see this feature in Tweetian but I can live without it.

Anyway, thank you very much for an awesome twitter client!
