1. It was just a suggestion.

2. I should have said "long sentence", not "run-on sentence". It's a
judgment call whether a sentence should be split for readability.

3. A run-on sentence results from joining independent clauses (or sentences)
without using any punctuation for the join.

4. Independent clauses joined using a comma, and without a conjunction, form
a comma splice, not a run-on sentence. A semicolon should be used to join
independent clauses (as you indicated), or the sentence should be split.
