Originally here at HP my identity was established as 'tsmog'. I used it for years back when chat rooms were the rage along with a forum presence. I use it extensively with memberships and as a reviewer such as Yelp, Amazon, and etc. An example is it is my member name at eBay where I had a store in a niche market for years. 'tsmog' stuck more than the store name did with patrons. My intent was extending that seeking a brand recognition here at HP, even though I never really wrote on that niche market.
It is comprised of my initials with 'og' added. That was a nickname acronym in the workplace for old guy. At chats and forums with close circles it stood for opera ghost. An intent was to add enterprises or Ltd. to it with a formal business licensing.
I really did not understand internet marketing especially with identities until the past few years. Consider I have been online since the early new millennium. SEO? Never heard of it until joining HP some four years ago. From that doing a simple search on Google I discovered 'tsmog' kinda' was hijacked by an entity or two as 'Tsmog'.
I can see how valuable a pen name or online presence that is with a niche market. Yours is a good example. Easily the RV lifestyle can be associated to Timetraveler2 offering plausibility, reputation, and a presence of expertise / authority in a niche market.
My offline pen name I do not really wish to be associated with an online presence. It does have a small reputation with poetry anthologies. I have submitted other works too using it without luck thus far. I wish not for it to be a part of my experiments with writing such as that of 'tsmog'. I'll learn from that for offline writing.
