Agree, more and more experienced and older players are leaving the business entirely (I personally know a few of them), or reducing their portfolio by dropping a considerable percentage of their non-performing domains.
I beieve there are 6 primary reasons for throwing in the proverbial towel (not necessarily ranked in any kind of order):
1. PPC declining so heavily over the past several years.
2. Higher renewal fees.
3. Difficulty finding good domain names vs the past (with too many having worthless names vs good keyword names).
4. Domainers giving up on parking and paying lots of money for development but often getting insignificant traffic and revenue from their sites.
5. Lots of internet traffic which in the past went to domainers now goes to places like Facebook, Twitter, Amazon.com and also to Blogs.
6. A growing percentage of portfolios is now involved with non-desirable and poor quality extensions, which get no natural or typein traffic.
Seems like more & more are throwing in the towel. Is it just me, or is there at least a partial capitulation going on with the domain market?
