We’d like to take a moment to announce TwitBin, our newest product we’ve been developing for the last few weeks. TwitBin is an extension for firefox that allows you to follow your friend and public tweets in Firefox’s sidebar. Almost anything you can do on twitter itself, you can now do from your sidebar (messaging wise, though not some things like adding friends).

As part of this application, we’ve introduced a new ad format for it as well. The new ads, 180x44px alpha transparent PNGs, are going to be sold in a hybrid cost per time and cost per impression. You will only pay for the minutes your ads are viewed. There will be more on this soon. If you’re interested in advertising with us, and trialing the new format, please contact us.
