I wouldn't tout another company if they did anything near the same, but just became aware of Obsidian Portal today. Lately, I have become aware of a few companies trying to do what Roll 20 are doing, and usually they are underwhelming at best.
I think we agree that we want Roll 20 to use their Kickstarter money wisely and keep focusing on improving their project in ways that make sense for them. Lately, I have been in one of the character sheet forums asking for character sheets to be added to the Roll20, and maybe it doesn't make sense looking at it.
I was wondering this, instead of asking Roll20 to add items like a wiki, character sheets, play calendars, ect.... how about partnering with a company like that to add in the features players are asking for, so Roll20 can keep doing what it does so well.
