I always hated monster and hotjobs because I couldn't get exactly the right search going and the listing I could find were too vague. I'd recommend posting your resume there anyway, you never know. My new favorite job search site is
www.flipdog.com. They supposedly pull the listings right off companies websites, it's super easy to use and find exactly what you're looking for and I always find at least a couple new contacts there.
Oh, for people looking for techie type jobs you have to check out dice.com and techies.com. They rock.
Also, something that really helped me was that book called Resumes that Knock 'Em Dead and the other book by the same publisher that's more general (sorry I can't remember the name.) They had lots of great advice about following up after you submit your resume, how to phrase things, interview tips, etc.
Good luck to you and other the other job searchers out there. Remember, persistance is the name of the game!!
