I’ve been here close to 2 years, and others have been 7. So using a year count would be self defeating.
Such a year count would only be relevant to topics about Quora. I’m quite happy with my somewhat adversarial, somewhat self parodying Quora credential as a Welchite. At any rate, I don’t think there is much to be learned about how Quora works, that you haven’t worked out within the first six months of being an engaged poster. (Well, that plus doing some research on the site.)
Being here for 2 years does mean I’m not an expert in being an “Old Planter” TW. And that’s ok by me.
