Some time ago I have published here in my blog Twitter bookmarklet and Facebook bookmarklet that allowing to select content on the html page and publish it to the social network. A day ago I got a bug report about memory related problem and now publishing updated bookmarklets. If you are using them or one of them, I recommend you to remove old ones from your bookmarks toolbar and drag the following ones to it.
Many thanks to Brian Carpenter for the bug report. Follow my blog to be updated.
