Some people say that blogs are ruining Google, but personally I think that
commerce is ruining Google more. For example, I recently read somewhere
that they can do drug tests with strands of people's hair. I was curious
about how that worked, so I Googled it. The first few pages of results were
all trying to sell me some method to beat hair-based drug tests, when I
wasn't looking to buy anything, I was just curious about the science behind
it!

Then today in the G&M (Roy MacGregor's column if you're looking for it, I'm
updating by email so I can't link) there was an anecdote about Queen
Victoria and green tea. I was curious about how urban legend this was so I
Googled it, but all the results were sites trying to sell me tea.
Apparently there's a Queen Victoria brand tea or Queen Victoria's favourite
tea or something.

Sometimes when I am Googling something I do get all blogs, but most bloggers
(not me because I suck that way, but most bloggers) do link to things they
are referencing, so I can get there. Blogs are more useful than 25
identical sites all trying to sell me something I'm curious about but have
no intention of buying!
