I personally like this idea since I do try to add descriptions and pictures for my own weblists and to my suggestions accepted by others. The ego in me also wants to get a little credit for going that extra mile for other items as well (e.g. official RIA lists and items added by others). Not as pressing as some of the other suggestions, but I must admit to some current hesitation in making this effort with an eye on what happens with this possible enhancement.

This is another one of those transparency things. Currently, any logged in user can edit a page (add a pic, add a description). It would be nice to have a record of who is making those changes.

Not a critical feature, but it would be a nice one.
