A nosey question

Probably absolutely none of my business, but as I'm feeling curious (AKA nosey) I will ask anyway. I glance at my blog statistics occasionally and have been wondering why so many people end up here so frequently from Brazil through searching for DDD8 in Google? Just curious, as it was an academic conference held in Sept '07 so I can't imagine it being still newsworthy now, either in personal blogs or elsewhere. Unless there is something specific going on in Brazil...? I mentioned the conference in a post last year, even though I knew I wasn't going, as one of my PhD supervisors was one of the organisers and I was probably feeling informative at the time. It would be interesting to hear from others doing research or work in that area, so if anyone's passing through again and if you feel like leaving a comment, it would be great to hear from you.
