After re-reading it a few days later, I realize it reads a lot like advertisement.

Some technical stuff wrt. SNI:

We waited a long time for the SNI-support to be widespread enough for us to provide to the customers. Despite we have a lot of users in the 'mom-and-pops' demographic, which typically tend to have older equipment, I'm not aware of widespread complaints about it.

It also turned out that most webservers can't handle being loaded with a few thousand SSL-certificates...

Finally, we were somewhat nervous about the rumored 'SSL/TLS has lots of CPU usage', but it didn't turn out to be an issue AFAIK.
