It appears that the new twitter share link can be used to break the 140 character limit. Basically in Firefox you can do this:
1) In the URL bar enter http://twitter.com/share?url=Some over 140 character text 2) Hit enter 3) On the page resulting page click "Tweet" 4) View in web and notice the limit broken I'm not sure if clients can handle this, but it could turn into a pretty nasty annoyance for users of web if it continues. Might be a good idea to have it looked at. I'm assuming a simple check to verify it's a valid URL would suffice.
