This blog's been up since 2009 and has almost 500 posts at the moment. So I have been going through and combining some of the posts that are about similar topics, in order to make them easier to find (so instead of there being 10 different old posts all on one topic, now there should be just one or two.) If you have an old link and aren't finding what you were looking for, try the search box at the right hand side of the page and it should come up.
This is going to be a gradual process so not everything has been combined just yet. I am also trying to improve the tags on old articles, making them easier to find, and taking time to update dead links in the blog posts. This takes a great deal of effort and time, and this is why the blog's not been getting updated so much -- my current focus tends to be on editing old posts over writing new ones.
