Appreciate all the feedback from the denizens of this forum.
Not a huge fan of the fact that they have said they were going to integrate with Mint for the past two years, and it doesn't sound like they are anywhere close to making that a reality. At the same, I realize their business model probably has them running pretty lean as far as staffing goes. So I suppose one can't have it all. At least with SigFig, I can manually create a portfolio and add stock shares for tracking.
I went ahead and took the plunge, using the OP's referral link - I guess we'll see what share Robinhood seems fit to gift me with. Anyways, I figure it can't hurt to have an account, especially since I probably won't be holding much more than one share of BRK.B for the next few months.
At the very least, I must say that I like the user interface, very slick and aesthetically pleasing.
