Pretty common i'm sure, my strategy is basically to play only hands I would play anyways. The exception to this is if i'm in the BB and can see the flop for free (of course), or if I'm getting 5/1 on my money with a good hand or 7/1 with just about any decent hole cards. I get my blinds stolen a lot, but when people stab at my BB and i'm holding AQ i usually sieze a decently sized pot. I'd be interesting to see, but i think in the long run i might actually be making money in my blinds. Of course this is at 1/2 limit, people are smarter at the higher limits.
