Hootsuite is not a pretty UI :)

So, isn't your filtering out a user the same as muting a user?

I just realized you can add multiple criteria (i.e. From X user, and Y keyword) ... that is valuable. I didn't realize you could do that. (Psssst - see, UX!) :)

I realize people want something pretty, and yes it's enticing but your question was why are people saying they love the idea, then signing up and not coming back. Do you have any user engagement metrics set up (using something like Mixtab) to see where the drop off happens? If you're seeing user growht, but low engagement it could be that the UX is not delivering on the value proposition.

Maybe get some friends/family who use twitter alot to sign up and give step by step feedback along the process and do some customer interviews.

We don't filter anything out, as that's against Twitter's ToS. We do however facilitate sending all tweets from a user into a folder you define. You can of course decide not to read that folder :)

The UX on creating filters needs work, I agree. You can make filters as complicated as you like! e.g. "Any links tweeted by @tweetdigapp with the hashtag #opensource".

We have metric tracking for most user actions. Home rolled though, and I've not heard of Mixtab. Will take a look at them, thanks.
