I did it last year and it was fun. This is kinda last minute but thought I'd check if anyone would be interested. I found it made the season a lot more enjoyable for me because I was vested in a lot more than just my team (Go Giants!!!). Pretty easy to keep up with (especially if you have an Android phone, you can just download the app and manage your team from that. I believe iPhone has one as well). I run the league through ESPN. Let me know if you're interested and I'll send you an invite (I'll need your e-mail address to send the invite). I'm hoping to get 10-12 teams.
If you're a huge football fan, you'll probable enjoy the heck out of this.
BTW, this is FREE.
