Other useful applications like ENS

Ens is the first protocol/project (not sure the correct term) that I have actually used and enjoyed using for a while now. This week after seeing the DAO creation process in full effect and spending a lot of time on the discord I want to get involved in other useful crypto projects.

I understand that useful is a subjective word so I'll specify the word useful as any product that an average college student can use. Its difficult to get this cohort involved in defi because there is a financial barrier to getting into it ( you need substantial capital to find use in any defi project). Most college students dont have those resources at their disposal.

Ens ,however, is a pretty straightforward concept, with a low financial barriers relative to defi. My friends who are usually uninterested by crypto can see the value in this project and some have even spoken to me about how they could acquire an address.

So are there any other crypto projects currently like this?
