Suggestions for a Startup Web Company

mochaone asks "I've always admired the Slashdot crew for putting together a great site that has vastly contributed to the internet experience. I have an idea for a website that I think has great potential also. I would like to know how slashdot (or any other webcompanies) got started and what tips they might offer? Should I use webhosting services or provide content on my own computers? What's a typical server setup -- separate boxes for web servers, database, banners, etc? T1 line or T3? How often should I backup data if providing content on my own computers and should I store backups offsite? Any other tips are welcome. More interested in the high-level, architectural issues rather than the "Use Debian over Redhat" or "Use Python over Perl" issues. I think those have been covered in other Ask Slashdot features. "
