Shame really - if you are going to make the effort to write a blog at all, it makes sense to me to make it available to the widest possible audience. With a personal blog there is little chance of anyone other than a small, dedicated audience ever being aware of it, never mind remembering to read it.
The Birmingham New Street blog was another great one on here, but once it left RMWeb, I wonder how many still follow it.
I suppose the thing that counts most of all is the models themselves, which I hope to see on the exhibition circuit from time to time - or maybe in the 2mm Magazine.
It's your decision, but it does seem a great shame.
