I have a simple "post about this article to twitter" plugin lying around which I quickly hacked up in the past. Some folks wanted something like that, so I have added it to this site. Its quite hackish but should mostly do the trick for now.
Also, I've finally updated the TinyMCE plugin for Wolf CMS to 3.0.0 final. For the Frog users out there, you should really upgrade to Wolf. I will no longer support the TinyMCE plugin for Frog or any other Frog plugin for that matter.
