I have created a Custom Search engine using Google custom search. I have set it up to only search the sites, blogs and technical resources that I have specified. I will use this search engine when troubleshooting and finding useful information. The point is to remove all the unnecessary hits you get from using the regular search engine and make sure I get hits from the brightest bloggers out there.
I have tried to collect good blogs and resources for Exchange and OCS and have made a list of the sites that are added. Try it out and please let me know if there are sites that should be in the search engine and I’ll add them.

Stale, good work on the search engine. I’d highly recommend adding in the pointbridge guys as well, good stuff on many of their blogs. Thanks for adding me to the list as well!

Thanks for the tip, Kevin! Added the blogs from PointBridge that I could find about Exchange and OCS.
Hi, Excellent job a great tool :)
Something to add from atea.se
http://www.cinline.se/
Will do, Tommy! Nice to see a colleague around here :)
Hey,
Add these too:
http://www.msexchangeguru.com
http://www.msexchangegeek.com
http://www.nitingupta.in/blogs
http://howtoexchange.wordpress.com/
Thanks for the input, added the blogs :)
Great idea, I’ll be using this for sure. Can you add these too?
http://www.mikepfeiffer.net
http://sysadmin-talk.org/
Sure, added them now.
I’ve moved my new content to http://blog.schertz.name, but keep the old URL in that last too as all my past OCS articles will stay online at PointBridge’s site as well.
Thanks for notifying me Jeff! I have added you new blog URL to the list.
