why do people regiser?

Perhaps they are not humans, but a script is registering users in an attempt to break in & hack your site?

Users with the role of Subscriber can’t actually “do” anything on the site but some sites will sometimes offer special, subscriber-only, content. So someone may have liked your site so much that s/he wanted to make sure that, if there were any “specials”, he’d be able to access them. That’s why this is a Good thing.

Don’t feel obliged to now offer subscriber-only specials. Many blogs don’t bother and people still subscribe as a way of indicating that they’re a fan of the blog and will probably be reading it regularly. Build up a reasonable list of subscribers and you might want to look at emailing them when you’ve added a particularly good new post (there are plugins for this) or giving them a sneak preview of something that won’t be on public display for a few weeks.

So registrations can sometimes be a good sign.

numeeja – I think a percentage of them could be just sniffing around.

esmi – Thank you for the informative reply. This helps me understand possible legitimate motives for people registering. I will continue growing my content and who knows, maybe some day I will offer something interesting to my subscribers.
