Like 'Internet Entrepreneur', I often say I'm a (full time) Web Worker, primarily because our industry's nomenclature is so skewed-up:
Good point, the real question is how many members make enough money from buying and selling domains to support themselves without any other income ?
If you buy and sell domains, you are not a "Domain
er".
ER: a suffix used in forming nouns designating persons from the object of their occupation or labor (butcher; carpenter; officer, doctor, lawyer, gardener ...).
In other words, if you just buy and sell meat you are not a Butcher, buying and selling wood does not make you a Carpenter. Buying and selling law or medical books does not make you a Lawyer or a Doctor. And buying and selling seeds does not make you a Gardener.
So, how is it that if you just buy and sell domains you're a "Domainer". It's a big word, that encompasses the Entire profession. Simply buying and selling does not cover "Domaining".
We all know that if you buy meat (etc. etc.) and try to sell it 'off the truck' you are a Scalper. Just like scalping Tickets. And, if you are also pushing ('parking') 'ads' -ie caps & jerseys from a table (site) .... then you are also a Vendor. But you are certainly not a 'Baller'.
Vendor:
Generally, a supply chain vendor manufactures inventory/stock items and sells them to the next link in the chain. Today, the terms refers to a supplier of any good or service.
Scalper:
n. One who scalps tickets to popular entertainment events: buying them in advance and then selling them (e.g. online or just outside the venue of the event), often at inflated prices.
n. A person on an open exchange trading floor who buys and sells rapidly for his or her own account, aiming to buy from a seller and a little later sell to a buyer...
A Domainer, is like a gardener / farmer... you buy the land/domains... layout the landscape plan -based on the needs of your crops / portfolio; plant the creative and physical 'seeds', tending ("developing") your crops / garden over time... from which you can harvest the flowers and 'fruits of your labor', until you decide to sell the land.
Also, "Developing" means
Working... "the garden" in whatever field... its not an end in itself... so the distinction (Domain Vendors) use between a ""Domainer and a "Developer" is a false dichotomy.
