Scrapboy may get me involved again in GooglesOrkut. Scrapboy is a little utility which sits on your "desktop" and whenever someone posts something to your scrapbook in Orkut it immediately pops up.

Nice idea, a sort of offline messenger. These types of utilities are on the rise, so i think i am going to put them in a seperate category. Offline Instant Messengers is like Scrapboy but i guess the private messaging in e.g. the phpBB may fall in this category too (is there a utility which watches your phpBB inboxes?). They have the property that your webbased inbox within a social site is enhanced by a small utility which alerts you whenever there is a new message and possibly the options to create a new message at the same time.

However multiply offers also a screensaver which shows you the latest posts from your network as a screensaver and the rssticker shows you in a scrolling mode all posts from possible your network (or any other rss) which acts in the same way. So maybe "social network utilities" is a better name.
