The following is a short rant intended for all those who design comment forms on websites:
When you have a box that says ‘homepage’ or ‘website’ it is absurd to make people type http://www.mysite.com. The HTTP means Hypertext Transfer Protocol. Every website in the universe uses this transfer protocol, so making someone type it is always redundant.
The same goes for ‘www.’ Homepages and websites are on the world wide web. They aren’t mail servers or any other sort of networked beast.
In conclusion, I should be able to type sindark.com and your comment form should understand it.
P.S. Even more unforgivable than sites that produce errors when ‘http’ and ‘www’ are lacking are the small minority that produce absurd URLs when you enter a site name in X.com format. I have seen sites where putting that yields a link to: “http://www.siteIamcommentingon.com/X.com.” Nightmare!
P.P.S. See www is deprecated for the argument that having to say ‘www’ is unnecessary in all circumstances, not just when filling out comment forms.
