In my first job out of college i worked at a big consulting company on a project at a company that used interwoven teamsite cms. Teamsite was a cms written in Perl, JavaScript, and Java with lots of xml sprinkled in. It was a horrible system.

I blogged about it on my personal blog. All the posts were about how to solve issues I had using it. This was before stack overflow.

After I had about 10 such posts I wrote a post titled "interwoven teamsite sucks" and linked all the other posts there.

I started noticing traffic to that post from specific ips accross the country.

A week later I was pulled into a meeting with the top see directors and told to remove my blog. Interwoven was an Accenture client.

I removed it.
