[Plugin: Sociable] Adding Bit.ly URL Shortener

I thought it would be nice to be able to shorten my wordpress url’s with bit.ly. I am already a bit.ly user and haven’t used awe.sm. Here is how I implemented it (this is a diff of the sociable.php [the one with the new features] and sociable.php.bak [the original]). This also lets enable this feature, add your API key and Username in the sociable settings page.

diff -b sociable.php.bak sociable.php

I would have liked to have changed this to include a radio button choice between url shortening disabled, bit.ly, and awe.sm but I just stopped working on it. I hope this is something that blogplay can implement.

Thanks,
