Instead of having to post each useful link I stumble upon, I decided to create 'Link Pages'.
These pages are arranged by topic, and I will be adding more links and link pages in the future.. This way you can set a Favorite of your own to a link page, and automagically, new and (hopefully) useful links will appear..
This also solves my problem of needing a centralized Favorites mechanism.. as I use a lot of different computers.
Btw, don't hesitate to put your own useful links in as a comment. (Hmm this almost start to sound as a Wiki :-))
