"I think that Commas are the most difficult punctuation mark to use. Out of all the punctuation mark rules, the rule for punctuation marks is the most subjective. I think semi-colons are similar, but don't have a as severe impact on a sentence if deciding whether to use them or not. All the other marks lay out how they are to be used, and as long as you can remember them, they are simple enough to do. Commas require interpretation of the how the sentence is constructed. For example: If you are making a point in one long sentence, you need to determine a point at which using commas is no longer effective and making a run on sentence".
