Stop using parenthetical asides (Score 1)

In previous stories you've asked for specific writing tips. Here you are: stop using parenthetical asides. This doesn't contribute to your point: (although I don't know what that limit is).

If you want to make this point: conventional email spam grew to unmanageable proportion, you should move that before the conclusion of your paragraph. You should also tighten that sentence up to something like: Conventional email spam grew to unmanageable proportions because anybody with an email server could send out millions of messages per day.

That one change will make your paragraphs more focused, and easier to read. I hope that helps!
