This is obviously an issue for lots of folk. I added some blogs to my reading list way back and some of the most interesting ones are never updated. I do think it all comes down to “why” you are blogging. If, like me, it’s more of a personal diary and it’s just open to other folk to read then it’s often easier. If you are trying to be all philosophical or topical then it can be harder to come up with good, relevant content.
As part of a recent relocation, I found an old notebook in which I’d written down some notes about a walk along the West Highland Way (in 1993). It was actually quite amusing and fascinating to read it back after all these years.

I’m looking forward to similar reactions when I look back at my current posts in 20 years time (if God spares me etc, etc, etc)
