Ask HN: Where to ask SaaS building questions?

There is a) StackOverflow - where we can't ask any broad question b) Hackernews - where these questions are not interesting enough. c) Blog posts - These do offer some interesting point of views but I fail to put them to practice. I am not trying to be a leech, over the time I've done a lot of things if I find people struggling with something similar, I will definitely help them. Where can I ask a question about SaaS architectures? I am pretty sure, many of us have technical expertise, motivation but lack experience. So, a place where people can review your stuff and provide some feedback would be cool. Is there any such place?
