Domain

I have purchased my first (and possibly only) domain.  http://www.bettyjj22.com  For whatever reason Bettyjj22 is my Instagram user name and since I have such a passion for photography I plan to use it for multiple places – like this blog.  I feel very much like a Queen of the Land who surveys her domain.  What a lovely word – domain.  Rich sounding and powerful.  Full definition below.  I especially like “a field of action, thought, influence”.  My humble blog has been enhanced just a tiny bit.
