My first comment came out a bit harsh. I keep returning to Nambu, but here are some gripes:

1. Clicking on an @handle in a tweet sends me to twitter.com instead of doing something within the app.

2. I'd love to see retweet tracking functionality handled as it is on the new Twitter.

3. I'd like to see better handling of user profiles than just sending me over to twitter.com

Basically, I've just started using the new Twitter because Nambu kept sending me over there so often.
