Matthias Ott, on personal websites as an alternative to social networks:

Personal websites are the backbone of the independent Web of creators. Even after all those years, they remain a vital part of what makes the web the most remarkable and open medium to date. We shouldn’t take this for granted, though. If we don’t pay enough attention and care about the open web enough, we might lose this valuable asset. So let us protect the Web as a source of inspiration, diversity, creativity, and community. Let us maintain what we have and work together to make this little part of the magic of the Web sparkle even brighter. Let us help new members of the community to start their journey. Let us build, prototype, publish, and connect.

Read this. And then, if you don’t have one already, buy a domain, get some hosting, and publish a site. There are plenty of resources around the web showing how to do so and you can even use a service like WordPress.com as a one-stop-shop to get everything you need all from one place.
