I used to use Dealupa all the time (and under its previous name Thedealmix), but now they've started to require an e-mail address to even look at what's available. No thanks.
Pull together lists of webinars, articles, online courses etc? Have a SmartRank (patent not pending) to prompt them in a similar way based on interests. This could teach you how to invest also, not just giving hot tips.
It's not that easy to figure out the best thing to invest in. And if you do figure it out and you convince everybody, the price goes up so it's not the best thing anymore.
Seems pretty similar to Betterment or a host of other providers (Personal Capital, etc). All these guys rely on the same thing: low-cost, large ETFs and the use of modern portfolio theory (MPT) to put together a balanced portfolio. The problem with all of them is the same - following MPT in 2007-2008 would have gotten you killed. All that being said, getting people to save and invest in general is a very good thing - so maybe there's the true value of the idea.
