Quite simply: is there a place such as DeviantArt, but purely for the purpose of sharing software (and source if preferred)? I'm aware that DA has plenty of software, but only related to customisations and UI hacks.
I recently came across some really useful apps I had made from way back and besides posting it on an online code hosting site or a personal portfolio that no one will ever find, is there some more community-ish places on the internet I've missed out on where coding mercenaries share and show off?
I personally host small snippets on my website, larger projects on Google Code, and use Ohloh to link them "socially" - this is for open-source projects, of course. Perhaps Ohloh is what you're looking for.
