You know what’s cool? When you subconsciously want something and a startup responds to your (unvoiced) requests. Well, mobile photosharing app Instagram has just made a very small tweak that has the potential for huge growth: You can now send your Instagram photos full size to Facebook, and they automatically display “beautifully” in your Facebook Timeline.

Photos shared from Instagram will appear in your Timeline with the original caption that you posted on Instagram, as well as a link to the public Instagram URL.

All photos posted from Instagram will end up in a special “Instagram photos” Facebook album, and you can share past photos full size by following the instructions here.

This is why this matters: Facebook users can reshare a photo posted on the their friend’s Timeline, therefore increasing Instagram’s reach to people outside the app and the potential of Facebook’s 800 million user base (it’s almost like Facebook is functioning here as an ad hoc web interface, no?).

Already I’ve gotten way more engagement on the first full size photo I’ve posted than any other Instagram share in the past.

Instagram has 15 million users presently, and both an Android app and video are coming according to reports. Instagram co-founder Kevin Systrom wouldn’t give me a specific ETA on either.

Facebook is the world’s largest social network, with over 500 million users. Facebook was founded by Mark Zuckerberg in February 2004, initially as an exclusive network for Harvard students. It was a huge hit: in 2 weeks, half of the schools in the Boston area began demanding a Facebook network. Zuckerberg immediately recruited his friends Dustin Moskovitz and Chris Hughes to help build Facebook, and within four months, Facebook added 30 more college networks. The original idea for the term...
