>The problem — at least from my perspective — is that flexibility is optionality. If one day down the road you want your site to be something other than a blog, but you are using Ghost, you need to go through the same sort of transition process I described above. This may actually be a Good Thing. Honestly, I can't think of many things you want to start doing where you want to adapt your existing blog. When you start on something new, create a new sub-domain or buy a new domain, install new software and go from there. I'd much rather focus on doing what you're doing now well rather than make a trade for speculative optionality.
