I got back from NASW last week, I had a lot of fun but was really busy. I found the sessions really useful, and I met a whole bunch of science writers and editors.
The ScienceWriters2010 blog was actually really helpful in learning what went on in the sessions I missed.
And it was a good experience to write a blog post about the session on statistics, I found the session really helpful and hopefully the blog helped others who missed the session.
Overall, a very useful and fun conference, I hope to attend again next year.
