Who Knows (www.whoknows.co.za) is a great website which has all kinds of interesting and handy contact details on it. (Please note that this web site is for South Africa only).
If you want to find a number of somebody who can help you with a particular problem (eg Loadshedding or your town council), look no further.
I have bookmarked (and blogged) it!
