It's also important to consider if TC readers are your target audience. I've seen big pageview spikes from TC and other widely- (or poorly-) targeted press coverage that didn't convert very well, whereas coverage in much smaller but better focused publications resulted in more overall conversions.

I'm not waiting; I have users. But I don't have 1000 users and would like to. The only suggestions in the list I haven't implemented yet are TechCrunch coverage and a (good) demo video.
