the recent avalanche of commercial edits in the Wiki, and the passive attitude of other editors not stopping this misuse of the wiki
The problem with a wiki, and wild accusations like this, is that the wiki keeps all the history of changes, and I don't see evidence of this in the Raspberry Pi section of the wiki. There was a brief upload of information about another embedded board, seemingly from a distributor, but it looked to me as legitimate board and expansion information rather than abuse. If anyone has a problem with the wiki, it is easy to report it to Wmat (administrator) who seems very reasonable to me.
The advantage of the current wiki, to me, is that the other boards on there complement the Pi for those that want to experiment with circuits and control systems (not something for me, at the moment). There are quite a few boards, and a lot of information on them to help people use them, although I have not followed this too closely.
If users search the wiki, just like searching the internet, the wrong search term will get a bunch of hits that may or may not be what they are looking for. I can't see how the wiki would be worse than the internet in general. When the users picks a page on the internet, they might find a one year old blog page, valid back then but now outdated. The blog cannot be changed; the wiki can. A well patrolled wiki can counter bad edits. Trying to distance yourself from the wiki will just lead to less involvement and your fears may be realised because of your actions.
I don't intend to analyse posts to the forum to see if there is a correlation of any sort over the dropping of the wiki link. There are lots and lots of posts covering a few common issues for the new users; bad power supplies, bad SD cards / image flashing and the initial set up to name 3. The SD card set up, troubleshooting and config pages of the wiki have these covered, but still they come up on the forum and many responses do not mention those pages
If you are concerned, it would be useful if you would create a new thread so regular editors can express their intentions and others can point out problems. I don't think it would take much to sort out the pages that new users would need, and the foundation wouldn't have to keep updating a beginners guide as things continue to change rapidly
