Two examples: I've had one
personal for quite some time (2004) and it's fun writing it and I don't expect any income from it, but it can be a pain in the ass especially when I realize I haven't being posting in few days time
Lately I have done few
commercial and I have to say I don't intend to earn piles of money on them (in fact if they cover their expenses I'll be happy) but I do expect them to bust up my other business models/sites and there is that
don't keep all the eggs in one basket thing, I had pleasure to learn few years back
For me these were the reasons I've started doing them, as well as the fact that they are something new so it really breaks Your daily routine, but ask me in few months time and I'll let You know was it worth it.
I'd say, for now at least, they can't make You much money but they can give You a boost to Your business, not that You need one
