Cyn, if people keep sticking semicolons into your work it's probably a good indication you are using comma splices instead of correct punctuation to break up run-on sentences. If you aren't sure what punctuation to use, keep it simple and avoid run-on constructions; assume that the reading public will know the difference.
Except in cases where a sentence is complex and has so many words or phrases set off by internal commas that a semicolon is needed for differentiation, think of a semicolon as a full stop between two
related but independent clauses. A clause has a subject and a verb. If the construction doesn't still work when you substitute a period for the semicolon, the semicolon probably isn't the right tool for the job.
That doesn't mean just use a comma to be safe.
Breaking up long rambles into shorter sentences generally makes for better writing. At the very least a writer must be in control of his own use of the language if he's going to communicate his meaning to others. The final product can be no better than the poet's ability to express himself.
