Hey, this is Darnell (from Inside Orkut).
Although the adds may be irritating to some people, they basically keep Orkut alive (as Google has to eat as well).
Before the ads, the “bad, bad, server. No donut for you!” errors were all over the place.
Now that the ads are in place, I’ve seen less errors and more features.
So, all in all I think they are a good thing. After all, wouldn’t you like to be paid for your blog content? (on your blog)
PS
Nice blog by the way.
Good to see another Orkut blog around.
