For me, one of the things that always seems to be missing in many hobbies is a solid wiki. Oh, they try their damnedest to consolidate data from ever larger comment threats and FAQ stickies, but lots of useful advice is only found after a user has been browsing a site for weeks.
A month ago a user requested a DIYDrones wiki, and the admin here welcomed the users to put one together, since Ning proved incapable of doing it. Then I realized - I can do that! I've just recently become involved in UAV research, and I'd like to find ways to help build the community, which is a matter of some urgency given the looming regulatory decisions. A thorough wiki can be one of the fastest ways to become acquainted with a topic you don't understand, and to cease fearing the unknown.
After a week of working on spam filtering methods, constructing lists of desired content and slowly adding stub pages myself, Dronepedia.com is ready for launch as a collaborative project, encompassing all facets of civilian unmanned flight. Virtually all of this hobby's knowledge base is chronicled in disorganized blog/forum posts that new users only tend to locate through a lucky Google search. I'd like to change that. Who's willing to help out?
