Erm, the OP was explaining that if you have already launched, your YC experience differs from what you might expect. Fair point I thought, and might be useful for those considering the timing of their YC application. I have noticed that some people feel that having launched already gives them more "cred" in the process, and the OP points the downside to that.
The funny thing about it, though, is that most of their problems during this time came from the fact that they were getting traction. I think these probably pale against the problems one has when one is not getting traction. Yes, not having users lets you keep building the product... but this is of rather less comfort when you're simultaneously wondering if anyone is going to use it.
