Wow - I tend to think I'm pretty CSS savvy, but I only knew of about a third of these. A good read for UI developers.

You never heard about them because most aren't supported by all browsers. Therefore, not all that useful (but interesting to know about in some cases.)

meh - it depends on whether you need your page to "look the same" on all browsers or to "look good" on all browsers. Making a website look the same everywhere is difficult due to browser differences, however, making a website that looks good everywhere is less so.

Take the "-moz-border-radius" attribute for example. In some cases, making a site that looks great in FF, but looks nice in IE is acceptable - especially when you know with relative certainty the target demographic.

That's how I use stuff like this too. I wouldn't want to do too much of it though. Proceed with caution ;)

At least one of examples in the article (font-stretch) is not supported by any browsers at all (AFAIK), and I think one or two are only supported by Safari. The list would have been a lot more useful if it was accompanied by a list of what browsers those properties actually work in.
