" One of the reasons why you need www or some other subdomain has to do with a quirk of DNS and the CNAME record.
Suppose for the purposes of this example that you are running a big site and contract out hosting to a CDN (Content Distribution Network) such as Akamai. What you typically do is set up the DNS record for your site as a CNAME to some akamai.com address. This gives the CDN the opportunity to supply an IP address that is close to the browser (in geographic or network terms). If you used an A record on your site, then you would not be able to offer this flexibility.
The quirk of the DNS is that if you have a CNAME record for a host name, you cannot have any other records for that same host. However, your top level domain example.com usually must have an NS and SOA record. Therefore, you cannot also add a CNAME record for example.com.
The use of www.example.com gives you the opportunity to use a CNAME for www that points to your CDN, while leaving the required NS and SOA records on example.com. The example.com record will usually also have an A record to point to a host that will redirect to www.example.com using an HTTP redirect."
Is this a good approach? FYI, I have a blog and not too paranoid about security between CF and my web server.

Ask HN: Why do we have asymmetric views about work life balance in professions?
Correct me here and this is a genuine question.We (software professionals) expect to go home at a reasonable time, still be paid the best salary among all verticals and we often complain about work life balance. But we have a different set of expectations when it comes to doctors, day care professionals, military etc. We don’t expect a doctor to discontinue his operation if he worked for 9...

This is a paranoia acquisition to kill a future competitor. If this works, and I think it will under FB’s strong leadership, its a win win for the tbh founders and FB.
If you care for a non-monopolistic future where privacy is valued, go work for Snapchat and push some sense into them; diversify and acquire companies like this to compete with FB (Even if you don’t like Snapchat).
