If you open source it, pick a license that's more restrictive (e.g. AGPL). This leaves a chance for you to get lucky and sell it to a company who wants it to use it as closed source so that you can buy a few beers. Otherwise they will just take it and use it without a single thank you. Probably I'll get downvoted for this but IMO releasing work under the BSD, Apache or a copyleft license that you created on your free time is like playing charity for large corporations.
