What do you want...?

Hypothetically speaking, what do you look for in a fan/hobby community website?

What's a must have in a journaling website?

What would it take for you to actually jump ship from say a site like LJ?

Would all of your friends moving be enough or would it be dependent on things like ease of creation, userpics, storage space, etc?

What are you willing to pay for? (special features like tracking, extra userpics, gift images, awesome swag? etc)

What do you love? (the following are suggestions only)
In LJ?
Dreamwidth?
Forums?
Reddit?
Tumblr?
Facebook?
etc

What do you hate? (see above for suggestions)

If this project were to happen, it wouldn't be based on the open source LJ code, so if that changes any of your answers, or gives you new ideas I'd love to hear them.

I'd also be interested in hearing opinions from folks not on my flist, and if anyone is so inclined please link folks back to this post.
