There has been another change to the way this blog works - a tiny change that is bigger than it looks. It shares the linky love. All registered comment contributors especially should read this. [Update: bug fixed, should work for all users. please report to me if not working]
If you are a registered user and if you have specified a website on your profile,then every comment you leave will be followed by a "(@)" with the @ linked to your website. Here's an example. Some registered users of this site who contribute comments DON'T have a website on your profile. Put one on and receive some linky love.
(And if you do have one, check that it starts with "http://". This link from a comment will still work if it doesn't but Drupal doesn't set it up properly for anyone viewing your profile).
When you post a comment on any Drupal site, the post is followed by your name (if not anonymous). If you are not a registered user, Drupal links your name to whatever URL you stated. If you are a registered user, Drupal links your name to your site profile ("user/nnn").
The link on the comment is one more link for Google search engines - one more bit of linky love back to your site. From a page-rank 5 site like this one, that is worth having. This is why I occasionally need to delete comments dropped that say "Great site, man!" posted by "fred" whose URL is "www.nudebritney.com" or somesuch. People get paid to wander round dumping this stuff.
I get a few pretty empty comments from sites in the ITIL sector too - I tend to leave them alone. Welcome brother - happy to share if you don't abuse it. You may recall that was something SpamWatcher accused me of a while ago. Where is that jerk now? He could do something useful like go pester the link-droppers on this site.
So if you don't register for the site, you get a link. If you do register, you don't. This didn't seem fair to me. So I fixed it, on this site at least.
You're welcome. Thanks for contributing.
