Sequoia is always ahead of the curve. This is good for entrepreneurs. Entrepreneurs are told well in advance about money coming from Sequoia. Even that article mentions that fact.
They have always been an early stage investor. They invested in Apple when it was run by two scruffy kids and nobody believed their "personal computer" story. Even the ones who believed were scared of IBM crushing them. They believed Yahoo guys and their Internet story when it was still part time project for PhD students. They believed in YouTube even though there were bigger players in video sharing market. They invested in YC company (sama's company) when people were mocking YC as place where "feature based" companies are crated to be acquired. They invested in YC itself when YC didn't have hits like Dropbox, AirBnB or Heroku. They never invested later stage at pricy valuations like some of the recent funds. Be it that "hot" startup that comes around the corner like Netscape, Facebook, Twitter, Tumblr and number of other dot com companies.
VC's are figuring out how to combat things like YC and number of micro funds. And here you have Sequoia, who is quietly doing things without any ruckus. That too for last 3 years. They saw the threat of incubators/micro funds before anyone else. And they acted upon it before anyone else.
PS. I don't work for Sequoia. Nor I'm their "scout"
