Just gave a quick look at the site statistics for the past month, and I was surprised to discover that 6 percent of my visitors have their browser language settings on Portuguese (either Brazil or Portugal).
These were all new visitors, by the way. And they came on different days and looked at different pages.
Not sure about why I had a burst (albeit a small one) of popularity among Lusophones, but I did attend the 2004 FIEC Congress in Ouro Preto, Brazil, where I presided over a session em português.
In any case, sou feliz de ter visitantes lusófonos ao meu blog.
