Keith's note: Yesterday @ISS_NatLab (an official NASA Twitter account) announced that "This official NASA ISS National Laboratory Office Twitter account will be shut down by October 1, 2012." and "Visitors are urged to follow National Lab activities at https://twitter.com/isscasis, maintained by Center for the Advancement of Science in Space".
That's fine but a little weird. Why not put "@ISSCASIS" in the tweet thus making it a lot easier for people to follow them using their Twitter account? @ISS_NatLab has 16,000+ followers. @ISSCASIS only has 1,211. Better yet - why not just give the @ISS_NatLab account to CASIS? That's their job, right? That way you keep the followers. Take the NASA logo off and add the CASIS logo. Meanwhile, a parallel NASA account, @ISS_Research, with 21,000+ followers remains online and never makes any mention of CASIS or @ISSCASIS. So you can bet that this dysfunctionality between JSC ISS and CASIS will continue regardless of how many Twitter accounts they have and what they call them.
