I get the idea PG says startups need to "do things that don't scale". When do you think this is a bad idea? Or is it? Is it possible to run oneself into a hole with this mindset?<p>Reference: http://paulgraham.com/ds.html
I think there are cases you can work yourself into a tough spot.. but even there.. if you receive significant funding full rewrites are possible and often done. However, if the thing that doesn't scale is directly related to your business model you may be in trouble..
