No need to use Pluggio. Just follow the daily recipe described within and you can do the exact same thing with Twitter & an RSS reader!
Re the price of Pluggio. I spent a lot of time getting to the current price points. I think the best thing I can say is try it for 30 days (no need for any kind of credit card, and it has instant sign-up) and then you can get more of an idea of how useful/valuable you find it with zero cost. At the very least you would get 30 days worth of following growth for free! Hope this helps. :)
I'll give the trial a shot. It really does look amazing, and I really am not opposed to paying something for it, it just seems to me (broke-ass student) a bit much.
Great way to solve a problem, however, even if most people don't know they had that problem.
