Usually this is fine, but sometimes it would be useful for them to talk to one another, albeit not in a creepy, Facebook, AI bot way. Thankfully, there is a handy app for that. If This Then That (IFTTT) allows you to set rules so that, when one thing occurs, another automatically happens.
For example, you can set it up to archive every @ mention on Twitter into a Google spreadsheet, to post on LinkedIn when taking an Instagram at work, or to text your partner when your phone battery is low and to do all this automatically.
It strikes me that, while this might be early days for getting one thing to work automatically for you, this could be quite useful for researchers. Imagine a world where you receive a message when someone enters a certain location (helpful if youre meeting an accompanied shop, say), or any Instagram posts from participants with set tags go into a centralised cloud drive for projects. It might take some working out, but living in a world where apps work harder for us could well become the researchers dream.
