If there are 6-7 callers and the action is on you to complete the blind, then I say go for it. Usually, you're sitting on a shitty hand, but the pot is unraised. And, you can see a flop for cheap. This is NL, so your implied odds are screaming. Especially with over 7 people in the hand.
If you hit a monster (unlikey... but it happens!) you can easily check, depending on the strength of your hand, and outplay your opponents. If you miss the flop, you can easily let go of the hand.
Which raises an interesting point: When you play low limit (and low "no-limit") holdem, and you miss the flop, don't ever be afraid to let go of your hand. As "novice" as this may seem, a lot of people waste too many small bets chasing, especially for the simple fact that the bet they are faced with is a small one. This simple discipline alone can turn someone into a break-even or a winning player, because the level of play at these low limits isn't *that* great.
Corollary: Don't let go of everything! If you hit a flush or straight draw, and it's in your favor to call (because of pot odds) then you should call.
