I think the Blaugust project, to get bloggers from various mmos to blog once a day, was pretty successful.
Personally I got distracted - by the AT at the start of the month then by World of Warcraft at the end of the month.
Still a discord was set up, there were some pretty interesting blogs to read and a chance for bloggers to build their sites by adding and being added to each others' blogrolls.
I'm pretty satisfied. I got a few posts up in August after a rather dry year till then and if I didn't blog every day then it was because I was absorbed in other ways to spend my leisure time.
Wilhelm (who didn't miss a day) has a more detailed analysis. It's definitely worth checking some of the listed blogs.
My favourite new blog is a Wow one: https://diaryofaguildleader.com/
