Ironically it doesn't help to use link shorteners on twitter anyway - all URLs posted to twitter count as 23 characters. The hypertext is the truncated original URL string, and the URL is actually a t.co link.
Shorteners these days are for analytics, not shortening per se.
Because this is a marketing channel. They handle tracking of FB/IG messages by other means, intended for engineers.
Yeah those links don't even work for me anymore as it's a tracking site.
What else would they use?
Something like meta.com/our_own_tech_handles_this
Not sure it's preferable to hire people at fb salaries to maintain a link shortener than just to use a reputable free one?
Every big company has one of these anyway, and usually more involved (internal DNS, VPN, etc). A link shortener is like an interview question.
They already have fb.com.
fb.com seems like a reasonable choice.
Their own?
their own shortener, e.g. fb.me, presumably
Not only that, the announcement is on Twitter, a company that at least used to be their biggest competitor. Old habits die hard, huh?
