No doubt about it, etail is here to stay in the hobby, and without a doubt it will change things. But not all change is bad.
I've been reading this thread with interest, because I have 25+ years experience in graphic design, a profession which has been severely rocked by the change to computer-based design and by the growing popularity and accessibility of the World Wide Web. Ours is no longer a trade that requires a college degree and years of experience to master, as everyone seems to have a 9-yr.-old nephew who calls himself a "Web desiger." What we designers perceive as quality has fallen by the wayside, yet our [former] clients either aren't aware of this decline or don't care about it. Worse, a formerly lucrative profession is one in which it is now extremely difficult to make ends meet.
There are many parallels between the changes in my profession and those in the marine aquarium retail business. The most important one, I believe, is that this change will happen and there's nothing you can do to stop it. The only productive way to deal with this change is to figure out how to adapt your business to it.
It's naive to think that my local LFS's offer such good advice and customer service that I'd be willing to pay them $12 for a jar of Chemi-Pure that I can get from DrsFS for $4.59. At one nearby LFS, the guy rarely looks up from the basketball game on tv when I came in and gee, I hate to bother him to ask about an interesting fish. The only really good LFS in my area is on the other side of town, nearly an hour's drive away in normally heavy traffic.
At another nearby LFS, helpful advice is usually only available when I'm willing to wait in line behind several customers. I asked that store's owner to order and install a custom system for me several months ago and every step of the process has been a disaster, from leaking sumps to shorted out pumps, parts that he forgot to order, skimmers that don't work, etc. After paying the store hundreds of dollars extra in hopes of benefitting from their professional expertise, I'm left with a huge, expensive, unfinished do-it-yourself project. Apparently his idea of "installing" the system was to glue the standpipe in and deliver the tank and cabinet to my house. When components the LFS sold me wouldn't work and he wouldn't refund the cost or come to my place to try to get them to work, I didn't buy replacements from them. Instead, I went to Froogle.com to get the best prices available.
With the level of customer service that I get from my nearby LFS's, I feel confident that, like digital graphic design, e-tail is here to stay no matter how much any of you complain about it or criticize it. The simple fact is that for many of us, buying livestock and drygoods online is a much better alternative. The difference in price and service between my local LFSs and DrsFosterSmith.com or LiveAquaria.com is like night and day. The "good doctors" are doing a fabulous job --so good that I'm modelling my own new e-tail business after them.
Graphic designers have had to adapt to constant computer-driven changes in our profession. I suspect that most LFS's are going to have to adapt to these changes too, because e-tailers are not going away any time soon.
