> Why did you decide to open source all of your personal projects? What if it became something great that you later find out could be sold for extra income, would you regret open-sourcing?

I think that's a decision to be based off of what it is. If that's a concern, and if open source has limited inherent value to you or the project, perhaps it shouldn't be.

For me, i highly doubt my currently projects will make any money. Primarily home automation, and home cloud-lite stuff, Storage, etc. Nothing ground breaking, and where it might be "ground breaking" (though it's not), i specifically strive to not have it be ground breaking - a pillar of my work lately has been simplicity, ease of use and ease of maintenance - being side projects and all, i don't want anything i write to confuse me in two years.

So yea, i have no concerns about it being open source - and so i default to OSS. If it gains any adoption, i get contributors, testers, UX requesters, etc, all things i want. So OSS is purely a boon for me, in these cases.

edit: Plus, i like being able to add a trail of work on my resume/site/etc that i'm proud of. For few side projects that i have left closed source, i split off as much code as i could making them into OSS libraries and such. Even if the core of it can't be OSS, some of it can i'm sure :)
