Abiro Trends is a new service that visualizes Twitter trends and enables you to set up trend events.
Without registering, you can see the latest worldwide trends graphically. You can click on a keyword or hashtag to perform a search for it.
After registration you can see trends over time for any region supported by Twitter, and you can then also set up one or more events.
For the time being registration is free. If you sign up now you won’t be affected by a possible commercial setup later.
