Is Adecco a good idea?

I've graduated college last December and have been on a on-going job search for the last year.. Everywhere I've applied to has either denied my applications or has given me the run around continuously which can get a man depressed. At this point I've herd some of my friends telling me about Temporary Job Agencies; such as, Adecco.... My question to who ever is willing to help is, Would it be a good idea at this point to get involved with a temp job agency if not for the fact of finding a new job but to get some experience built up under my belt? Any extra information that you have would be great as well because i'm just trying to get my facts and options together.. Thank you..
