I am working on a Twitter block for the *nuke community and just released my first beta. I would love to get community feedback... I haven't completed the AJAX pieces yet and unfortunately, for now, it is built solely for RavenNuke(tm) (I'll eventually support other versions as well).
Here is my full news release describing the block in more detail as well as how to get it:
TegoNuke(tm) Twitter Block 0.1.0 (Beta) Released - Montego Scripts
