So me and one of my friends have decided to start a software review website (iphone). We're looking to build in user reviews, search, categories, etc. It doesn't seem to make sense to us to start from scratch when there might be existing back-end software or frameworks out there to help us, but we're having trouble finding them. It seems every other day I read about a new company that's made building sites a whole lot easier, but a Google search on the subject seems to turn up a lot of SEO-ish, spammy or "make money now!" type sites that seem very shady.
So we thought we'd ask here. Have any good solutions slipped by us that people know of? What are other sites out there built on?
If you want to go simple, WordPress is a pretty good option and can be extended as needed. But you'd probably have to do a lot of work on your own to build in the product database part of things, since WP is really more of a blogging / simple CMS platform. I hear Joomla is also a good bet, and more powerful, but I haven't yet tried it myself.
