After submitting an answer for this PPCG challenge, I decided it might be cool to try playing around with Stack Exchange's web sockets. A first interesting idea I thought of, just to play around, would be to monitor a tag, and figure out stats on questions posted, like how the frequency of questions asked changes throughout the day.
Would opening potentially several web sockets (and maintaining them by responding to heartbeats) cause any kind of issue to the network? Obviously, me alone opening several sockets isn't going to be significant, but is the use of web sockets, in general, a strain on the site? Is this a service that should only be used for certain purposes?
