I hate how so much event sharing is on Instagram. People, you have a website. Use it.
@mayintoronto it annoys me when local activist groups are like "we're doing a <political thing>! details available only on our <facebook and/or instagram>"
I think it's mostly an access thing where it's easy for people already using those sites to post information on them versus making a website (or finding whoever has the login key for their website and getting them to add it).
