Having your own space on the internet that you control helps a lot. In the last 20 years I have seen a lot of websites/platforms come and go. Twitter and Facebook will probably be gone in the next decade. When you have your own space, you could actually put effort in maintaining it.
I have been looking in my archive of tweets, blog posts on third party systems, bookmarking tools, and forums to build this website. Also looking backwards, I think it is nice to have it all in one place. I am not done yet, thousands of bookmarks/tweets/post to go through. In the end I will have an archive that starts in 2006 till now on my own website, cool to see how interest change and how I develop as a person.Peter Cammeraat
