Is kanji (especially hyogai kanji) more prevalent than usual on Twitter, or is it the opposite?


Since it is very easy to input kanji on computers or mobile devices, I've
always wondered if tweets have more kanji (particularly non-jouyo kanji) than
typical Japanese text, especially since kanji characters save character space.
But on the other hand, tweets are very casual and slangy.




People rarely use hyogai kanji if reducing the number of characters is the
only purpose. For one, usually hyogai kanji do not drastically reduce the
number of characters, so it's simply not worth the effort. For one, as you
have correctly guessed, using rare and obsolete kanji make your tweet look
fairly odd. Lastly, the 140 character limit [has not been that compelling for
Japanese
people](https://blog.twitter.com/official/en_us/topics/product/2017/Giving-
you-more-characters-to-express-yourself.html):

Basically, most people write text on Twitter just like they do on a blog site
with no character limit. Still, people sometimes replace words that are
normally written in kana with a bit difficult kanji versions ("かえって" → "却って",
"むしろ" → "寧ろ", ...).
