Would you find such an App useful? Please vote and/or comment in the
User Voice section.
I envision an Events App building upon Events in 1.3 that would support ES communities as users market, promote, research, and review events by integrating related social media. It would help showcase events either "live" (i.e. scrolling window of activity) and/or be useful as a way to archive events later (i.e. configurable by admin to save any particular social channel content) . It could integrate with the ES stream, ED, etc.
I've written a little more detail in the
User Voice area.
For illustration, take a look at the Joomla! World Conference 2013
social media archive implemented with
eventifier. Similarly, you could see all social media from a #hashtag at a
US College implemented with
getpressi. There are also free scripts to get started such as
SpectragramJS.
Imagine some instantiation of those capabilities for ES events with appropriate limitations and/or reliance on CDN to be sure it's not unwieldy and otherwise out-of-control
