Every page on your blog, whether it's the home page, the individual post page, or an archives page, has what's called a title element. Depending on how your blog is set up, this information probably displays at the top of the browser, and in the tab where you have that page open if your browser does tabbed browsing. As someone who often has a lot of tabs open at once, I really appreciate being able to see which tab is which because of the page titles.
To make your blog more accessible, though, are there any special considerations for what should be in the title? I've blogged before about how special characters in the page title sound when read by screen readers, but what about the content?
The page title is the first thing that screen reader users hear when they get to a page, so it's great if it actually tells them what the page is. If every page on your blog has just the name of the home page, that's not so helpful and could even be disorienting if a reader goes from your home page to one of your posts, or vice versa. If the page title is your blog's name, then the tagline, then the name of the post, that's a whole lot to listen to before knowing exactly where you are.

As someone who uses a screen reader I want to say that page titles are very important. Every screen reader I know of has a command to read the window title, which in a web browser, is whatever you have set as your page title. Making these titles distinctive and as much as possible reflective of where the user is in terms of site navigation is a big help over generic titles.
