I"m glad the wiki has been mentioned… here is my view point on it (no doubt not 100% correct, and just my outlook on it).
1) eLinux has allowed the foundation to use their wiki space, as far as anything else this makes it the official wiki, even if it isn"t living under a raspberry pi org address.
2) Yes, it is your wiki, you"ll get more out of it if you put stuff in and no single person can do it (not least since no single person will do everything everybody else will want to do). If you have no place to put stuff, and are willing, then the wiki is as good a place as any for you to do it, and anyone is welcome to do so (this is why we"ve tried to make it easy to find a good place to put projects, info about your groups etc).
Also, just ask if you want to put something in and need some help…there will be someone who will be more than happy to do so.
3) Information will be spread around the internet (kinda how it works really)…there is no way around this, there are so many groups and individuals with their own interests and uses for the RPi that is would be unreasonable to expect them to all add what they are doing to the wiki.
All the wiki can do is be a starting point for people, hence the "hub" concept. I feel it should be seen to be different from a library of information (sorry h2g2), but more an airport to find where you are going.
We can put information in there about the device and how to use it, but similarly we can also link to other great work which is going on elsewhere. Even before release there are several very strong communities growing out there and I think that is great, the wiki can just provide a way to find these communities and hopefully a few shortcuts to some of the excellent information that is being generated (wherever it originates from).
Ideally, we can also save some effort by linking to things, rather than feeling the need to duplicate the same things over and over (that way we can look at new stuff and move faster going forward). Also there are groups which are doing very detailed documentation (Frambozenier.org Documentation Project Datasheets for example), who will welcome help, plus the educational material which is in the works.
Hopefully the wiki can be the go to place to put your links to your blog or your project or group so that all the excellent content which does get produced, can be found and seen. You are welcome to create your own space directly in the wiki too.
Similarly if you see anything good, then put some links in.
4) Finally…one big hurdle I have is without a RPi, there is not much more I can personally add yet. Even the Easy GPIO guide is stalled by this, since I am reluctant to recommend hardware modding until I"ve physically tried it myself. What I have done is speculative based on alternative hardware so far, but I"ve purposely avoided the more interesting/useful stuff until I can be sure I"m not just writing a "how to blow a raspberry guide".
If Eben thinks kids are getting excited about what colour the snake is in their program, try adding wheels and flashing lights to a rpi and see what happens!
Now some work…what areas need more detail in the wiki?
Currently the games section is lacking and I would love to see more links to blogs/projects which are encouraging kids to try things out.
I know a lot of us love the technical detail, but what things do people need when they open up that box, particularly any kids which are lucky enough to get one.
Finally…a shameless plug…if you want to write some useful stuff then also consider getting involved with the MagPi community magazine….http://www.themagpi.com/
Will be starting to look at content for issue 2 soon.
@naicheben thanks for the mention!
Note: When searching all the raspberry pi pages should be categorised as "RaspberryPi" so it"s not too hard (if we provided instructions…) to filter out anything else.
