I did not mean to be difficult but it does seem very odd to update a blog purporting to give accurate and reasonably up-to-date info when in fact much of it is several years old! That's just not fair to readers, in my view, the more so when there have been lots of changes in the interim. It would be far better to date each article with the approximate time it was written rather than changing dates and years. Without that, it becomes far too obvious to some that something is not right with them. After all there are other much more recent blogs with more accurate info. Why try to kid new readers to your blog that your articles are as accurate - when they are not? Merely a suggestion, but I think a more than reasonable one.
