Ask HN: Will other social networks follow Twitter's 3rd-party restrictions?

Twitter has created a precedent of a previously very developer-friendly service switching to a position where 3rd-party clients are strongly discouraged and limited.

I wonder if you think that Facebook, which might also be pressed for higher revenues given its lackluster IPO, will also follow suit and start limiting what 3rd-party apps can do?

What about other "free" social services? Instagram? Pinterest?

I believe that services like Flickr won't impose this limitation since they provide paid accounts to their customers, which is their source of income.<p>The free and popular social network services are the ones that I'm worried about.
