Of cause, most Google+ tools will become obsolete by the time Google releases the official API. On the other hand, getting into it is a typical nerdy approach, that I love: Play around with the newest toys, see what can be done with them. Personally, that's what drives me in this case: Learn something new, do some creative coding (without having to invest too much time like working on a 'real' project), provide something useful for those, who also already tamper with it, have fun. And maybe we stumble upon a useful idea, which can be extended, once the official API is out. In my view, that makes it worth the effort.
