Re: Oddly enough...
Why would anyone worry about being monitored while micro-blogging? It's a public forum where you EXPECT people to listen to you!
Twitter direct messages, for example, are not public. Not only that but governments do employ join-the-dots technologies too. Adding another dot is trivial to them.
"I'm being followed by MOSSAD", "So what, I'm being followed by FSB and CIA".
How are you supposed to know the true identity of that random account that follows you? There are Twitter accounts that follow many people but never utter a word. Maybe they are just shy folk or simply like earwigging...who knows? FWIW I'm one of those. I use Twitter to follow news sites; it's not a two-way medium for me.
There's a big difference between monitoring a public forum and the, sometimes related, arrival of an unmarked van in the middle of the night to take you on an unexpected holiday at a re-education camp
Good luck sailing that van from China to Australia. Don't forget your lifejacket.
