I have been reviewing a lot of other people's writing recently. More than is likely healthy. But if you ask me to read and comment on your stuff, I have one simple rule: lay off the fucking semicolons.
At the very most, semicolons should be like rare birds - exciting to see once in a while because of their rarity. They are not the type of punctuation to be used with reckless abandon, rather they often represent a poor compromise. Do you want your reader to stop, pause or what? Why have you left an incomplete sentence dangling there? Make a call, but don't abstain from voting here.
I can let one semicolon in a manuscript slide, so use it wisely. Any more than that and we're going to chat.
