I love the concept of an open, accessible and interlinked world wide web, but I think that we're slowly going more and more inside a walled gardens model, where your data, your content and even fragments of your online persona (of your digital self) is contained inside fortified silos like social networks. That's the main reason why I've kept this dumb blog for more than 15 years (at the time of writing this post), and will keep doing so for as long as I can.
When recently Davidfq wrote me and told me that he liked my blog and "all the IndieWeb thingy" I wondered what was that indie web movement. I won't go into what's about, so go check indieweb.org and come back once you've read the basics.
I already have some microformats setup for my blog posts, but I wasn't using the h-card anywhere, so following the getting started guide I've now fixed both my landing page and both posts and pages from this blog.
I think the IndieWeb is a great initiative, and everything is decided openly, so if you keep a personal blog I encourage you to give it a try.
