There have been recent discussions (and less recent ones) about karma. The karma found on any member's profile is based on what the person leaving it wants to say, or feels safe to say.
As such, it is limited as a tool for evaluating potential cuddlers. The number of karmas generally reflects some percentage of the number of cuddles they've had, but not always. When looking at the number of karmas someone has, it can be useful to look at how long a member has been on the site.
Karmas that are specific about why someone was a great cuddler may hold more weight than vague ones.
Related to karma, I believe, is the area of forum posting. While there are guidelines, there are gray areas and there are problematic areas not covered by the guidelines.
One of the filters I use when posting, relates to the fact that my primary purpose for being here is cuddling. I ask myself whether my post will have a positive, neutral, or negative impact on my chance of cuddling in this community. I see it as writing my own karma.
I'll put this out there with my cuddle enthusiast hat on: I want others to have the success here that I've had. My approach has worked for me, and I invite others to do the same. Most people do, to be honest, and others do some of the time.
