"We tried four tactics to get customers:"<p>Interesting that all the tactics were online. I wonder if visiting solo practitioners in the developers' neighborhood would have done any better, both for finding such and for getting feedback.<p>In any case, as a solo practitioner who charges more than $100/hour for my time, I would balk at $19/month because I'm not time limited. I might have paying work for 20% of the year (>40K/year), but the other 80% time doesn't pay at all. I'm not going to pay $228/year to get more time to read Hacker News.
