I don't *follow* it per se but do have the point plus calculator on my phone ... but listen up, there's something EVEN better!
If you have a droid phone, search for WW ScanCalc.
Ummm...according to that, my Coors Light that I'm currently enjoying is one mere point. Yahoo! :)
Not sure if that's points plus but I can probably figure that out if necessary ...
Excuse me while I run to scan some more items :)
