You don't necessarily have to write them yourself. You can just copy and paste from different sources multiple times a day.

(Sorry. I'll take your downboats and be on my way. I could not resist.)

Wait, are you telling me I can copy paste content on the Internet and get credit for it?

I believe this is called "Programming" in certain enterprise circles.

IIRC Twitter already enforces a max-height on tweets (ever since they allowed line breaks). People may indeed copy/paste but it won't add to the visual noise in timelines, and relatively few people will click through anyway.

I think the term of art in this case is "retweet".

Sadly it is pretty common that someone copy & paste some witty tweet and get attention. There's even a service to discover that. In Japanese it is called pakutsui (pakuri (= plagiarism) + tsui (= tweet)).
