I don't have a website, and plenty of people have already criticized my book. can't see why it would be required. However, a website is a playground specifically designed to get the word out about yourself. You don't need it, but it certainly helps.
Get a free Facebook page. No website until you're famous.
Methinks you need a dictionary and a thesaurus much more than you need a website.
I'm not being funny but if your website displayed as many errors as your post
you would be at a disadvantage before you even began.
I would suggest your own website then all you create has a central home that you can use as a portal to aim people towards where they can buy from. You also have 100% control over the content (if it's not a free site) unlike places like Facebook, which are mostly handy to use to point people at your website.
Myself and my friend combined know everything there is to know, but he's not here.
All of my marketing points people to the product page at Lulu for the product I'm promoting.
