Have you heard of Pinterest?
It's a "visual bookmarking site." I'm totally addicted.
It's exactly what I need (I used to rely on my brower's bookmarks toolbar, but that makes it hard to find projects and artwork-- Pinterest's "picture pinning" is much easier), but at the same time, it's exactly what I don't need (another time killer because I enjoy spending waste time browsing other people's pins).
Pinterest is still in Beta mode, so if you would like to join the fun, email me at ShealynnsFaerieShoppe{at}gmail{dot}com and I'll send you an invite. :)
