You can use it, but you're swimming upstream if you do. Fewer buyers, fewer sellers of things you might want to buy.

Sure, but if you don't use it you just make that worse. Of course if Craigslist had died where you are then there is no choice. However where I live Craigslist is still active enough that I can afford to ignore anyone who isn't there.
