I think this is an excellent idea. The challenge I found is getting enough people to commit to blogging and updating.
I look after the blog for Security Stack Exchange and through the last few months it has been impossible to such to our one blog a week aim, despite a large active community,mostly because people have been very busy - so a blog needs someone to be constantly chivvying and herding folks to contribute.
Here on Music.SE we do have some people with extensive knowledge of theory, practice, technique, instruments etc so I would hope it can work here.
Step one: identify volunteers, their areas of expertise and how much time they can commit.
If that looks like it will work, we can request a blog, and get things started.
And on that note, I can write a couple of posts on playing live rock gigs, or guitar effects etc
Couple of links we had as discussion questions when we first built the Security blog:
Volunteers so far:
- American Luke - theory
- Alexander Troup
- Rory Alsop - live gigging, electric guitar, setting up blog
- JCPedroza - DJing, sound design, electronic music, algorithmic composition, synths, software, and their convergence with music theory, practice, and performance
Update 15 May 2014 - Grace Note has pointed out there will be a slight delay due to resource constraints: the SE team have obviously been working on major changes with the meta.se and meta.so split, various sites going live / merging etc etc. I will check in with Grace again soon to check expectations.
