For anyone who was in any doubt...

The excerpt I put in a quote box was written by me, not taken off the Internet from some hapless victim. I wrote these lines to underline my point that some words and phrases can derail the effort to evoke a Regency sense of time and place. I don't think you have be steeped-in-the-method scholar of the era to be jarred by a phrase like social network. As to words like hi and alright--well, maybe someone new to the historical era might not find these obviously out of place, but there are others who would be put right off. Personally, I could not read it. I was gagging a little as I wrote it.
