Clippycorn is a pretty obnoxious fellow, popping up all the time and saying stuff. After a while, though, you realise that half his comments are actually useful. Maybe not to you that much, but they would be useful to a newbie
What I propose is that we keep Clippycorn--in a less obnoxious form. Expand his vocabulary to other help messages, and prune all the April Fools' stuff. Also get rid of the Microsofty feel. There, you have a tool that's actually quite useful for newbies!
To make him less obnoxious, we ought to get rid of the clippycorn (sniff) and turn him into an expandable dropdown/tooltip or something. Maybe prune down the obvious stuff as well.
Since most of SOs users are tech-savvy, it may not be that useful on SO, but the rest of SE could certainly benefit from it. The faq isn't that useful all the time, and obviously we can't stuff it full of all the details. But we can stuff lots of links and helpful stuff into Clippycorn.
