Just some notes here, not fully formed.
1) Murderati blog is the future. Several writers who work in a genre, contributing a post each week.
2) A writer should be writing, not blogging.
3) By sharing a blog, a writer can concentrate on writing books and needs only a skeletal personal website for book pimping and contacting.
4) Daily blogging can become bloody tedious (I know: I did it nearly straight for a year).
5) I know there are other group blogs, but Murderati is the first one I’ve come across — and it’s actually more of a blog than the others I’ve seen, which are more like “Here is my post about Writing Subject X” — those posts are more article than something personal.
6) No publisher should get the idea to do this. Because a publisher would never allow this line, from this Murderati post:
And may I just say here that IT IS TOTALLY FUCKING AWESOME.
Publisher: You can’t use the word “fucking”!!!
Writer: But I do in the books of mine you publish! Often!
Publisher: But that’s … different.
(Yeah: Fuck you, publisher!)
7) There will always be exceptions to writers blogging. John Scalzi and Warren Ellis, for example, do mostly daily posts. I wonder if they’d ever drop that for a lighter posting schedule in a group blog?
8) It wouldn’t be possible to have one blog for, say, crime fiction, and have everyone in that genre contribute. There are too many writers. But it would be possible for several writers in that genre who particularly like one another’s work to combine to do it (I think here of, for example, Anthony Neil Smith and Victor Gischler)
9) Each of these blogs should from time to time pimp another such blog, to spread around the reader/buyer wealth.
10) It’s always good when one writer mentions another writer.
