I'd like the community's opinion on the best way to convert to a multisite setup. Let's say that I have a blog that has several hundred posts already at myblog.com
I prefer that the main site in a multisite network be reserved for admin use and not as the everyday blogging site. So I prefer setting up example.com as the primary site and importing myblog.com into the network. Now when I add new sites they are subdomain.example.com or domainmapped.com
Am I just being silly here? Is it perfectly ok to convert myblog.com into a multisite network, so that add on sites are subdomain.myblog.com?
