There are 22 posts this month. That's not bad at all. It's not very many either (but the quality of the writing is top-notch). Participation in Carnival of Evolution is down. It seems Carnivals are a thing of the past. My guess is that social media has made this particular form of sharing blog-posts superfluous. I hope I'm wrong.
The number of different people who submit has gone down significantly. CoE now relies on a few regular contributors who submit their own as well as others' blog-posts. Notably Bradly Alicea (who has been active for a long time) and Charles Goodnight, who is a relative newcomer to blogging. Charles writes about theoretical evolution once a week and shares his posts via the CoE Facebook page. But I fear this is akin to biological systems of low diversity: they are more likely to go extinct when the system relies on a few generalist species.
I suppose it's good news that science bloggers don't feel the need to boost their readership by sharing their blog-posts with the 357 people who are subscribed to the feed on Facebook.
Interested in hosting this summer? Months open are July, August, September. Still a few seats left for those who hurry.
