Nature Network turns 3 years old today (https://web.archive.org/web/20120611031820/http://blogs.nature.com/nautilus/2008/02/happy_birthday_nature_network.html?), and it has been a very interesting ride. I wasn't around when Nature Network started, but posted by first Gobbledygook blog post (the blog had a different name back then) in August 2007. We passed the 50.000 comments milestone (https://web.archive.org/web/20120611031820/http://network.nature.com/people/U6E5B2CE1/blog/2010/01/26/nature-network-blogs-receives-50-000th-comment?) just a few weeks ago. And we were told that big changes to the blogging platform underneath are imminent.
I have had many, many positive experiences in these 2 1/2 years. I learned a lot about science publishing and met a large number of very nice and very clever people both online and offline. I wrote about 160 blog posts and an uncounted number of comments during that time, and writing blog posts is still a lot of fun and something I like doing on a regular basis (I decided a while ago to aim for one blog post per week). I am also excited about the upcoming Science Online London 2010 (https://web.archive.org/web/20120611031820/http://www.scienceonlinelondon.org/?) meeting, although the exact date and location have not yet been set.
Happy birthday.
