f2f is important greed and there is problem flying someone over 4 times over in year. Heck even more. It's the idea that it has to be the default. I work remotely but when we brainstorm an idea we like to fly to a site and hang around there for a week, white-boarding and socializing afterwards.

Timezones make communications harder as well, etc.

However I'll take these downsides vs the upsides.
