It's because you're not articulating what you're offering.  The only information you've given is that you've managed to kind of install a somewhat working version of ckpool for solo mining.  You're hoping to attract developers, programmers and "serious users".  If any of those types of users wanted to, they would simply install ckpool on their own and not bother trusting that you may or may not have done things right on your side.  I mean, really, what is it you're offering here?  I trust -ck and his solo pool.  He wrote the mining code and the pool code.  I hope you're successful, but you had better clearly and concisely communicate what you're offering.  Right now it's pretty vague.
