I think Twitter has a lot of "myspace risk". They are currently sort-of-cool, but many of their users constantly complain about the service. Their clients are extremely clunky to use and their 'feed' algorithm is laughably bad. A superior alternative would be relatively easy and straightforward to code (and several exist), it's just network effects keeping them alive. People are starting to realize that the way Twitter is designed reinforces and encourages reductive language, hot takes and extreme opinions. With how much they've gained already this year, I think they are a pretty risky buy. Hell, if Trump stopped tweeting the share price would probably drop 20% overnight.
