The only thing with dry logs is it iwill require you to slow down a bit compared to when it was green. I cut about 8 walnut logs for a local farmer a few years ago and he said they had been stored in his dad's barn for 60 years. They were dry as a bone. Sawdust was DUST! it cut fine, just a little harder than it would if green.
Use a new blade and you should be fine.
As far as activity, I think all this world of misinformation more folks are getting involved and pushing back.
I have a ton of pictures I need to get posted as I finaly got my 100x40 wood storage building built! Now all my cut wood will be nice and dry inside the new building.
