I have noticed this a lot lately, so I thought I would be
a know-it-all helpful and maybe shove some advice down your throat help you… if I may, that is.
OK, here goes.
If you start a tweet with someone’s Twittername, it will only appear in your follower’s stream if they follow that person as well.
This, my friends, is why you see some people starting tweets with a period before the @name. To trick Twitter into seeing another character there, thus NOT starting with an @name, thus making their whole group of followers able to see the tweet. (Not because those people just have big thumbs that flop around on their iPhones, as @mochamomma suggested.)
At first I thought this whole idea was as stupid as the RT feature (I prefer to manually RT so I can control it, cough cough @ev, @biz, just sayin’) – but now I see the wisdom of pulling out tweets when I am not mutually following someone. It helps cut down on the chatter, and almost gives you three levels of communication. DM for private, @name first for semi-private, and then full-throttle balls-to-the-wall public.
OK, so maybe those guys know what they are doing.
