Most projects here are something to program. I get a list of ingredients that I can put together however I like. Since I already have ways to program I don't feel like I'm in the target audience. Now if they were something I started to use, I'd probably end up programming them over time.
I tend not to worry about this question, because of how I think about this community. It's to bat around raw ideas, prototypes and experiments, but hallway usability studies here are not a replacement for getting out of the building and engaging with your target audience, whoever that is.
(Unless you consider the people here to be your target audience. In which case lack of uptake means some assumption is getting falsified.)
