It'll require me to wait until whatever number of people're online to read and review it, stopping rushed apps and possibly delaying mine a whole lot more than the regular ones (since I usually review stuff right away and am almost always online). It'll require me to write up sample posts that're good enough on their own, without a solid bg or personality to help me - which could prove to be even more difficult than a regular app.
What I judge the most about an app is always the sample post, anyway. It seems really pointless to write up an entire app just so that people won't be uncomfortable that they have to do it.
