Well, I'd say don't go looking for 'the one' in a rebound situation. If you feel the need for occasional pick-me-up dates or hookups, sure. But, as I posted in another person's thread, dating anyone within 3 months of a breakup is a 'rebound' situation, and is likely not stable.
As always though, it's based on individual circumstance. I for one wouldn't date someone who'd just gotten out of a relationship recently. They need time to heal completely (regardless of whether they feel they are or not) and sort out all their head-crap before I'll get involved. Safer that way.
