Twitoria is a web app that allows users to quickly find which of the people they follow on Twitter has been inactive so they can decide whether to continue following them, or not.

Features:

• easy-to-use and good-looking web UI
• only need to enter Twitter username (not password)
• user selects inactive period to display (week, 2 weeks, month, 2 months, 6 months, year)

The Good:

If you are into keeping tabs on those you follow on Twitter and want to prune those who have little or nothing to say, then Twitoria is an excellent tool for the job. All you need to do is enter your Twitter username and select the time period of inactivity you want to filter, and Twitoria displays a list of those who meet that criteria including their last tweet and its date. We like the fact that no password is required.

The Not-so-Good:

Twitoria really is easy to use and quickly identifies those on your list who don’t contribute much. Having said that, there were a couple of things we noticed during our test drive: 1) there is no auto-unfollow feature – you have to manually follow the link back to Twitter an unfollow from there and 2) there are ads displayed right in the middle of the displayed list of inactive users – we didn’t have a big problem with that, but some might.
