I answered these questions more intelligently yesterday but they didn't post for some reason.
1) I post trip reports on forums and pictures on the evil "thebackpacker" site (
http://www.thebackpacker.com/pictures/user/toejam.php - don't go there, it's evil). The pictures look really good on this site but need to be broken up into chunks smaller than "Texas Park & Landscapes."
2) I like to do detailed reports with pictures but usually don't have that much time to kill.
3) I would definitely look at other people's stuff and would use it myself if it didn't take much time to do.
5) The issue is ease of use - if it was easy and convenient I could pay a little.
Keep up the good work, Shannon. You're one of my cyber heros!
