Have you ever tried to remember, Google's IP address? If you do memorize it, do you use it to go to their site?

I guess I'm just bein a smarta**, but what I'm getting at is that domains are very important.

you want something easy to remember, otherwise you may as well just give the customer your IP address to remember.

For example:

thisisadomainnamethatisfartoolongtoorememberandwil lprobablyloseyoualotofbusiness.com

While:
buymycrap.com is a lot easier than the above, or even 156.366.31.75
