If you don't want to annoy lots of people with big assed posts on their dash... Use the page break function. Makes things so much less huge.

Spread the word!
This adds a "Read More" button to expand the post.
Note: This also works when reblogging. Even if the original poster didn't use one. Also I often see reblogs where the original poster used a break and the reblogger didn't.
I'm just going to keep reblogging this. Thanks to the people who do it regularly!
