I’ve been using Twitter since we did the Web 2.0 course about 4 years ago, but I really only started using it serious about 3 years ago.
My account was originally @sauvblancgirl, when I was just playing around with it. When I decided to start using it more seriously, I wanted to choose another name that was more professionally acceptable, but still a wee bit clever. I had a discussion online with @thewhaanga (Hana), and we played around a bit with some options.
We settled on @genebrarian – a mash up of genealogist and librarian, which fits with my role as family history librarian. I used the account to start up networks with librarians and also those working in the genealogy / family history industry worldwide. This has been very successful for me, and I’ve made quite close online friendships with people who I’ve subsequently met up with at conferences.
I find Twitter really handy also, for letting people know about events and news regarding my place of work.
But I also talk alot of nonsense. I know I’ve made mistakes in the past, hopefully I’ve learned from them, as I’ve gone along. Hopefully, I will keep learning too 
With the advent of Google+, I find quite alot of my genealogy “friends” are now on there instead of Twitter. So I try to remember to visit there too – and feel I really must get more serious about it!
