Can some one please check the grammar in this sentence.

Urn I quite agree tho the trend is away from the comma

It's grammatical without the comma.

With the comma it's ungrammatical because you're creating two dependent clauses. With the comma you'd need to write something like, "more power, it means more customers."

For emphasis you can use italics, "more power means more customers."

True, Blue

Again, true, Blue, at least technically. However it's done hundreds of thousands of tines a day by many whom you at least believe should know better

The rule as I remember it from my spent youth, "You can use a comma anywhere you think a slight pause is needed"

Thanks guys, if it can go both ways then the way it is fine. Really appreciate it!
