Two other thoughts on SoFi -
They recently changed their referral widget where I can see how many clicks my link got, how many people signed up from the link, and what commissions I have pending. Previously, this data was all anonymous with just transaction numbers. Now I see the email addresses of the people that signed up. That seems like a bit of a privacy issue to me. I just thought I would put it out there for discussion and for people to think about before using the link. It wouldn't stop me from using the link, I would just use an email address that didn't have my real name in it. I can't see where the person clicked my link though so I wouldn't be able to say "oh, that's so and so from the MMM forums." Since I share my link in a lot of venues it makes it more anonymous but if someone only shared the link here, for example, they would know the emails of the people that signed up.
Also, when we were discussing federal protections lost, I thought of some protections gained. You can't be a federal employee with federal student loans in default. Your tax returns and social security checks can be garnished for failing to pay federal student loans. I don't think private student loans have as broad collection rights like that. Obviously, people on MMM are planning on getting out of debt but if "it" hits the fan, its nice to know there are some limitations to the company's reach.
