I wish people just knew what RSS was, and what RSS readers are.
With E-mail being pretty unreliable these days unless you use a big provider (Gmail, Mailchimp, etc.)[1], people mostly uses IM tools for all their communication (messenger, hangouts, txt, slack). Even the last company I was at, I barely checked my e-mail and used it mostly for logs.
So something like this will pretty much turn messenger into another useless platform people will ignore, but it's because we already ignore all those other noisy platforms. ¯\_(ツ)_/¯
