The new Mac app Favs looks pretty nifty (hat tip to Shawn Blanc), but I don’t see why I’d use it instead of Stellar.io. Stellar is free, handles all the services I use, and works beautifully on my iPhone 4S.
I have an extra invite to Stellar available right now. Tweet me if you want it.
If credit card debt or student loan payments are killing you, I highly recommend taking a look at SoFi. Their low rates and incredibly quick and simple application process might be just what you need.
