Please take some time to read my article about hosting types (shared hosting, vps and dedicated server) and make suggestions, all comments are welcome! http://www.buraak.com/2011/03/22/which-one-is-suitable-for-you-shared-hosting-vps-or-dedicated-server/ Thank you
some of the information having some error. yes, some of the share hosting only applicable for single domain, but nowadays there are tons of share hosting able to let u host more than one domain names
thank you for your comment, I also stated that if you pay a bit more you may have multiple domains on single hosting account. For example an introductory GoDaddy shared hosting allows only single domain hosting (economy hosting), but deluxe hosting allows you to host multiple domains.
