Currently the situation is like this: the site is still running at full price, but the update frequency has gone down the drain since around the end of 2007. There were promises of a site relaunch, of improving the update frequency (webcams, candid pics etc) and basically nothing of all that really happened. The subscribers were treated to maybe one or two updates monthly, Kari sometimes shows up in the chat (like once or twice a week tops).. many "veterans" of the site started leaving and Kari still keeps telling everyone how unhappy she is with that, how she'd like to change it etc.. and yet, nothing happens.
Content-wise you'll get the full archive of her Pics, Videos and Candids, albeit with around a 1GB daily download limit imposed. That's still enough to download all the content she has ever produced (minus the GGW video, of course) in about a week.
And even then you'll have downloaded a clothing catalogue with only one model - the site always was "non-nude", and still is.
There is the occasional nipslip or semi-seethrough piece of clothing in an already fading video frame and somesuch, but that's usually nothing to write home about, and I certainly wouldn't pay 30 bucks for just that.
Concluding this sermon I'd say: if you're a collector and want to just grab all of her content (although you won't see her nude), go for it (and be sure to scan her forum for posted webcam vids). After all, she's pretty much the hottest girl in the non-nude business. If you plan on staying for the community or updates, though, prepare to be very disappointed.
