If you find a weblog you like click through the blogroll, if you find someone bookmarking the same site you have check out the rest of their links etc. Here's a real life example:
MediaSnackers is on Twitter. We got an email this morning that someone new is following us. We checked out their twitter page and clicked through to their weblog to discover their role as the instructional technology facilitator for Lee County Schools, in North Carolina, USA.
After some more clicking and reading we found out some amazing examples of teachers using wikis, sending newsletters out via SlideShare plus a great post with a huge list of resources (most of which we haven't heard of before).
Follow the digital breadcrumbs folks and you never know what pearls you will find.
