How many freakin domains do I need??

GULP! OK, I have a question for the experts here that have mega domains. I only have half a dozen or so. HOW do you keep track of them? where they are housed, passwords, admin passwords, usernames? good grief, I think somebody said it is a nightmare. I believe it.

I can hardly keep with the one few that I have. I would really like to know how manage them and if you use roboform how do you line it out?

is their any difference between. info and .com domains as far as adwords and Seo go?

I have bout a dozen but one main domain. I definately will be growing those to about 50 by years end across 3 or 4 separate hosts. Heard the big search engines watch for cross linking with sites that have same IP addresses.

Oh yeah and I know that it is important to save money, and every little bit counts, and all the rest of those sayings but MY GOODNESS, are we truly worried about paying an extra dollar or 2 over an entire year per domain????

I understand if we are talking about maybe a few hundred (buying in bulk) but just picking up a few dozen or even just a few here-and-there does not seem like a big deal..... or am i missing something?

I have about 10 or 12 domains but will have a minimum of 50 by years end. Its the "throwing it against the wall" method. You just throw as much as you can and see what sticks, then go with that.

Oh yeah. I know a dollar saved is a dollar earned & waste not and want not and a bunch of other sayings about saving money BUT are we really worried about spending an extra 1 or 2 dollars over an entire year??????

I understand if we are buying in bulk, like maybe a few hundred at a time but most of us are not. We are talking about maybe a few dozen at most if not a handful here and there. Am i right, or am i missing something here??
