LOL. Curmudgeons are good. Reality check.
The key to using social media for business is automation. Those updates are created once, copy is checked through Legal, and stored until a timer kicks them out to all the social media sites silultaneously for most companies.
The "Wall Post" thing is more a tool to stay in touch with seriously far flung friends (think wildly different time zones here) than anything. That and it aggregates news that caught the attention of like- minded folk so you don't even have to look for it.
Most of the time, Twitter (#1 by far), PoA, or Facebook links beat even the daily Aviation News sites by two to three days on most stories now.
The Russian crash was on Twitter only a couple hours afterward for English speakers, probably much sooner for Russian speakers. Reno crash was minutes. Etc.
I got an e-mail today with the text of that 787 training thing -- that was posted here almost two weeks ago -- and most of those e-mails say "First I've seen this!".
I gave up mentioning they're a couple weeks late unless they already know about PoA. If they do, I send 'em the three page and growing discussion/post URL.
AvWeb scoops most other sites as a traditional style news outlet.
EAA has significantly more content than anyone else on a wider array of topics.
AOPA is where I read month-old news usually.
Twitter is nearly-real-time but unvetted and works its way toward accuracy fairly quickly -- but takes a few hours. The discussions bring out fact-checkers who clarify on the fly.
FB seems to be where announcements of aviation events hit first.
