I searched my user name of choice, Garden Gerty, the other day. I have been on one discussion site for six years. Members of that site know that it uses our quality posts on other websites that it owns. That is part of the funds that they pay users with.
I always assumed it would be political posts, or controversial posts that would be of interest to them. Not my style of posting. Low and behold I searched for dear old Garden Gerty and found two new websites that I liked. I am quoted on both. It surprised me. Entire discussions picked up and put there. One was about making reading fun, and the other one seemed to be related to running a household.
If you have a single user name that you post with, try searching for yourself. Gives new meaning to the term "finding myself."
