Oh yes, I don't know if there's such a thing as SteamFolk, but SteamPunk looks like a right good old laugh, what with all those computer keyboards made of redundant typewriter keys, funny old stovepipe hats and swirly Victorian graphics. If you want a pure unadulterated SteamPunk novel and possibly the first of the genre (although not bearing that appellation) I recommend Keith Roberts' 'Pavane'.

I think Steamfolk is whatever the heck you want it to be, as AFAICGIS it doesn't exist outside of this thread and there's only about 3 people arguing about it here.

Swerving the thread towards 'Which was the first steampunk novel' would, from what I've seen elsewhere, take it into hitherto unimagined realms of bitterness and entrenched positions!
