I know from email correspondence that he has, from time to time, thought about the future of his blog. Now he appears to have decided to call it a day for good.

What a great shame that is. Scottish Unionist did a fine job of exposing the rotten nature of nationalism. His eviscerations of the borderline illiterate Cybernats who pollute the Scottish blogosphere were excellent.

This may have led to the blog been a bit one-note and too negative. Plus, the knuckle-dragging nature of Cybernats is somewhat self-evident. But the case cannot be made too often.

The personal experience that Scottish Unionist has gone through while facing up to the aggressive nationalists has been truly shocking in some cases. It spoke volumes of Scottish Unionist as a person that he always conducted his debates with dignity, treating his opponents with respect — much more than a Cybernat could ever achieve.

I echo the sentiments of Jeff. I doubt that the Cybernats really need to be tackled — they discredit their ideology enough with their own words.

But Scottish Unionist was more or less the only person who frequently visited the constitutional issue, at a time when we could be facing a fundamental referendum in the next couple of years. Perhaps the rest of us should step up to the plate.

I was delighted when Scottish Unionist asked if I would write a guest piece for his blog earlier this year. You can still read my piece about a vision of a federalism in the UK.
