Not long ago I purchased TextExpander from Smile On My Mac. It's a handy little program that inserts long snippets of text when you type an abbreviation. Like when you type "ddate" TextExpander can automatically insert the current date instead. This can be very handy for coding or writing HTML.
Sure, the software is nice, and the price was not ridiculous, but what really impressed me was the email I just received. Smile on My Mac sent me message full of tips for using the application. Keep in mind, I already paid for the software. I'm not using a demo so they are not just trying to lure me in. I think they just genuinely want their customers to get the most out of their product. That's refreshing.
