I guess the 'average domainer' consists of mainly those who come into domaining and last about 2 - 3 years as owners of domains.
In the first year they have entered domaining and registered a wide variety of domains 'because' they seemed to make sense at the time.
In the second year the first real hurdle arrives - the dreaded renewal fees! Here is where some will fall out of domaining, suddenly they are asked to pay for the renewals without having made any sales in the first year and therefore their 'dreams' are shattered. (This group I think are those who will buy a lottery ticket with more than a hope of winning but a belief they will win.)
For those that do pay renewal fees at the start of the second year most will refuse to do so again at the next anniversary of renewal fees, to these people they see domaining not now as a business but rather now a shoddy game and they will baulk at the very idea of investing in domains as to them it has become a waste of money.
Now those domainers who instead work at domaining, whether full time or part time, the first 2-3 years I think they treat as an apprentership in the industry, they study domaining, everything from what sells and where, how much for, who buys domains (both other domainers and external non-domaining businesses), they narrow their field/s of interest into which they will generally invest their domaining shekles into, they become ardent listeners and readers of news, are members of forums to pick up trends etc. (and not just domaining forums), these domainers will still 'punt' on registering or even purchasing domain names but be willing to change their mind and write off any investment in these domains should they not hold up to the initial promise (though they will generally try to sell them even at a loss to recoup some of the investment), but this now makes them a different kind of 'average domainer', they are now the 'experienced average domainer'.
So I think the 'experienced average domainer' is someone who no longer talks about their sales generally, someone who has developed interests in a wide variety of topics but a better knowledge than the general population on certain topics that are the essence of the subjects of their portfolio of domains.
The 'experienced average domainer' is neither rich nor poor through their domaining, they are long term investors which are willing to wait for one of their domain seeds to blossom into a magnificent flower which they shall benefit from the sale or development of, and be happy with the result for themselves.
Oh, and one other thing, an 'experienced average domainer' will be thick skinned - for they will have learned to ignore the insulting offers for their domain names from other domainers and wannabe owners of their domains. (I remember getting a derisory offer that literally was 'insulting' from a well known member of the community for a domain of mine, my reply was simple but not rude, I simply asked which minute of which day of which year did he want to rent my domain for, I am glad to say he got the message.
