I've been using WikiTree the past couple of days - very easy to use. I was going to upload my GEDCOM, until I read their note, which states that I'd be responsible for every profile I created with that GEDCOM. Hundreds and hundreds of people - yikes!
So instead I'm starting slowly, with my direct lines first. As I get more comfortable, I'll add in Husband's direct lines, then collateral relatives. Hopefully this site will stay free and I won't get all the upgrade advertising that Geni brings.
