Phenomenal post by ex-Blink COO, Ari Paparo, on why Blink (a bookmark service a bit like del.icio.us) died after raising $13M before the Internet bubble burst.
There's so many lessons to be learned here. Plus, I had friends working at the company. Ari is great for sharing all of this with all of us.
I personally prefer www.furl.net over del.icio.us myself!
