When the current government's people/offices use social media, I wish they would choose names that reference both their role and the current administration. I don't want the next administration to come in and delete all the old content (whether that be the Whitehouse press secretary's tweets, the blog of the state department, or similar). Ideally, such accounts would just stop getting new content, and be available as a record.
I also wish they would stop tagging all the Youtube videos of the Whitehouse Press Conference with 「Gibbs」, as he's moved on.
I'm not entirely sure about this, but maybe even whitehouse.gov should always be a redirect to a separate gov domain for each separate administration. I want all those URLs to work forever.
