I was even able to find a blog of one of their workers – Paul's Journal – though he doesn't seem to talk about his $job too much.
It is hard to post about $job, because very little of Bloglines backend architecture is considered public information. For example, from the companies Blogging Policy Document:
"It is the Company’s policy that all employees, agents and contractors must keep confidential all information about IAC Search & Media or any IAC company’s operations, products and business activities that has not been made public ..."
Which I believe pretty much includes how our custom distributed filesystem works, or how Bloglines is scaling (other than saying that memcached is awesomr, which is public), or even the details behind our new Atom Parser. It isn't something I am too concerned about really, you don't see anyone from Google posting the technical details behind Google Reader. It is just a standard in so many coporations to keep information close.
As Requested in the $job Blogging Policy Document: "The views expressed in this blog are my own and do no necessarily reflect the views of my employer."
