Yup...I'm guilty 27 sites up in 3-4 months, roughly another 50 more domains locked and loaded waiting for me to index them.
Only difference being I am invested heavily invested in Master Resell Rights, PLR, and kick ass minisites! (Roughly 6,000 products since January)
Now for the fun part... build several WP sites, amass a social network of thousands, build backlinks, learn SEO, figure out Camtasia Studio 7.1...and ultimately start driving massive traffic to it all!
I don't know what scares me more....having learned things I never thought possible?
Or
What I'll do when all this hard work is done, and the traffic (money) starts rolling in, and all the little hindrances become known (i.e. glitches, bugs, download issues, refunds, emails, auto-responder maintence and follow-ups, dead-links etc...)
I have literally acquired 70+ GB's of files, templates, squeeze pages, training products, info, graphics, content, articles, eBooks...etc... It's mind boggling
Oh yeah, and then setting it up to find affiliates who want to make 60% commissions selling my shit!
I sincerely believe of all the prior addictions I survived...the internet could very well be the therapist I needed....as it is without question the equivalent to that which sex, drugs, and rock-n-roll was to me in the 80's...sorry, had a little flashback there.
PS- In regard to your last bit, I just upgraded to a HostGator Business Account, unlimited domains....like $150-$180 per year, and with all I have uploaded, I have only used like 25% of the alotted (unlimited...lol) storage space. Eventually, I'll upgrade to either VPS or my own servers and reseller account. I think within the next 6 months actually
PSS- IMO Buy domains rom GoDaddy, set your DNS to HostGator...much better hosting provider. Again, IMO
