for those of you, using Twitter and twittering your blog postings there, this might be interesting:
Since your blog URL, sent to Twitter, usually is very long, Twitter uses (for some reason) tinyurl.com to shorten this URL. I did not want this to happen, because tinurl.com might be the largest URL shortener, but it's way too heavy for me and does not have a feature, I really wanted:
Previews including high-resolution thumbnails of the destination website.
I've started my own URL shortening project: http://unfake.it/
And I wrote an API, which makes it possible to shorten URLs directly out of WordPress.
I use Twitter Tools (written by Alex King), added a tiny little patch and left the rest (including author, credits, ...) untouched, since Alex did a great job and my intention was/is not to steal his work.
My patch totally bases on Twitter Tools (currently version 1.6b1) and may be downloaded here: http://unfake.it/twitter-unfake-tools.zip.

And see a demo of the website-thumbnail-tool here: http://unfake.it/qiX*.
So long and take care, Thomas
