One site Jeremy is using is this:
For those that inquire about the type of camera Jeremy uses: He used to have a Nikon D5000, but now according to that stats on the 500px site, he uses a Canon EOS 50D. In one of the Little People, Big World "specials" on TLC, viewers saw Jeremy return home and ask Matt and Amy to buy him a new camera.
He also has an Instagram which is a photo hosting application for phones that you can view online via Webstagram.
Jeremy also has a public twitter account:
If you're wondering, he does not really interact with LPBW fans on his twitter account. In his 200+ tweets, he has responded to fans a few times with a "thanks" -- such as when someone was praising him for being a Christian.
Jeremy also just started a Facebook Fan Page which is connected to his account on the 500px site.
Jeremy had a couple of public Facebook fan pages in the past which always ended badly. Usually, he would rarely use them or interact with people. Eventually people would voice their displeasure and discuss the several reasons that they thought negatively of Jeremy. Often times his friends would begin posting to Jeremy on the fan page with messages such as "Jer, what is with these losers on your page?"....then people would point to that as proving their point....and eventually he deleted the page(s).
On this new page, Jeremy lists himself as a Public Figure with the message:" Follow me on twitter: https://twitter.com/#!/jeremyjroloff and follow me on: http://500px.com/JeremyJamesRoloff
