Ask YC: Do you take startups in the same space as ones invested-in in the past?

I've been considering applying to the upcoming Winter 2011 YC intake.

The problem my startup is trying to solve, however, is quite similar to one of the startups you have taken-in in the past.

Both of us are tackling the same problem, albeit differently. I was curious to know how you guys think about this, for e.g conflict of interest, whether it would decrease my chances of enrolling, etc...
