I actually use Evernote for this all the time: I have a note with a list of new acquaintances along with descriptions and how we know one another. Like:
Becky: Friend of Kellie, works at UT. Likes chicken n' waffles.
At Nau's: Omar is young. Lulu is young. Gilbert is older.
While this method is far from ideal, I don't see Evernote Hello replacing my list anytime soon.
