Re-raise preflop for info, continuation on flop

I like re-raising preflop for information with hands like AKs, AKo, TT-QQ, etc. Here's a hand where I got that information, but it didn't really work out. When he just calls the re-raise, I know he doesn't have a monster, however, is it right to bet out on this flop? Or when all rags fall, should I just check/fold?
