I just started using TextExpander and I think it's great for a lot of things. One of the main things I use it for is for when I have words that I often misspell, when I type the misspelling TextExpander automatically changes it into the correct spelling if I have it set for that word. I also have it set to change a key combination like "htin", then TextExpander will change that into "Hello this is Name". Overall I think that this is a great app.
