To be quite honest... And this is just my opinion. If your taking force from this well I'm sorry...
Based on what I have seen the "What Do You Look For In a Boyfriend/Girlfriend" seems to be a good concept and therefore if there was a poll against that to keep it or trash it. I would vote to actually keep it. Because I seems to be a thread where you can learn some pretty important lessons from other people. But yeah then it comes to the BF/GF thing irl... Its all up to you xP.
But as for the "Finding Your Special Somepony" thread. I cant say I agree 100% with this as there is dating sites out there already... But if it works for you... that's great but come to remember that you are on a Forum. Not a dating site. I'm not fully against it. Unless somebody in the future gives me a reason for me to be against. I haven't seen any conflict regarding it yet so in my eyes at the moment it is not really a problem... and again unless somebodys make it a problem...
