Is there any niche Search Engines for Technology guys?

[Alam]

My primary audience is coming from the technology background. Are there any niche SEs focused on technology? A SE frequently used by technology guys for their info updates etc?

I am marketing my products worldwide so if they exist anywher in the world, it will help me.

Check out knowledgestorm - I think they are what you are looking for. Seem to be the most widely used tech search.
