Usually the number of daily visits to my blog chugs along at somewhere between 15 and 20, sometimes reaching an average of up to 30 if I add new content daily. So I was surprised by the march 14th peak*, shown in the diagram above.
A little closer investigation, using the sitemeter tools, shows that this is evidently a direct consequence of a specific post I made wherein I mentioned that I might be reading "Don Quixote" in parallel with Viggo Mortensen. A great number of those 130 visitors ended up on my blog following a search on the name "Viggo Mortensen".
What I found strange (and kind of nice, really) was that a surprisingly high proportion stayed and poked around the blog for several minutes. Obviously Viggo's got a highly discerning fanbase.
*: Still nowhere near the all-time daily record of 1500 visits for the June 1st post (explainable by having been linked to on the Genentech intranet).
By the way, I do not recommend equipping your blog site with the sitemeter "extra" statistics module. Although it's not hugely expensive ($6.95 a month), it's almost guaranteed to cause you to waste huge amounts of time, if you have even a mildly obsessive personality. Questions such as who might be visiting your site from Palau or Tuvalu, or who your stalker in Kazhakstan might be, will just haunt you incessantly.
