Some topics such as Certification standards and the like are potentially better written by committee than by a single person. Is this a doable thing?
In a sense, all posts on our community blog will be written by a committee, as every post will be proofread and possibly edited by the editorial team. There is absolutely no reason we can't co-author posts, provided that at least two people are interested in writing the same post, obviously.
Even if you can't get someone interested in splitting a blog post, we can chime in and help in smaller ways. Only thing you have to do is ask for help, in the blog chat room.
There are already synergies forming on some of the post proposals on Trello.
