I actually thought of this first (So that there is not need to format the hook to 120 chars) and post it on a blog and pipe it to twitter, but general mentality would be people will only the first link from twitter(from what ever client) and would close the browser and would never visit wikipedia page. My script would use bit.ly api and embeds the link to wikipedia article itself with the 120 char text to post to twitter through its api.

 

Thanks :)
