Two degrees of separation?

I've commented before on how my blog readership list is all interconnected. But I discovered something new today. It seems that Huggies, a regular reader of Di's blog, is also reading and commenting on Brooke's blog. Now I know that Huggies came here once when I posted my story about how I met Stu, so I guess it's possible he may have made the connection then. Or perhaps he got there of his own accord, which would be even more freaky - I mean what are the chances of happening to see someone comment on a blog that you only read because you saw a link once in another blog you read, and someone *two* thousand kilometres away also happens to be reading it?? But then again, the internet is rather a strange place :)
