Without a read I might consider not raising this river. You might lose an overcall, which you didn't, and the bettor might not call a raise if he was just betting top pair, but perhaps he did.

There also used to be a lot of discussions here about raising w small PP on the button, which is +EV although a lot of people used to argue against it. Since you have at least one read that a weak player is in the pot, along with a poster and other limpers and you have position I think a raise preflop would be another way to play the hand.
