I have renamed my blog back to "Galactic Interactions", the name of the blog that I started when I was still an assistant professor of physics & astronomy. After I started working at Linden Lab, I noticed that I wasn't blogging about astronomy all that much any more, and what's more I have to admit that I was feeling kind of sad that I wasn't spending the time thinking about physics & astronomy that would lead me to spontaneously blog about it. As such, closed down my blog on scienceblogs.com and started a new blog entitled "Second Sight".
Life changes. I no longer work for Linden Lab. Also, over the course of the last year, I've become involved with MICA, which has made me more active in the astronomy community -- not as active as if it were my job, but it does give me a connection that allows me to keep it up on my own time. Especially given that MICA was founded by people who work in N-body calculations (i.e. the computational/theoretical arm that goes into dealing with, among other things, galaxies interacting), it makes sense for me to rename my blog back to "Galactic Interactions". So here it is!
I may be changing the look of the blog a bit in coming weeks too. Being the nerd that I am, I don't find themes or anything like that. I hacked the PHP and HTML for a standard WordPress theme to get the current look, and I may hack it a bit more to make it more appropriate again to its new/old name.
