Another vote for self-hosted Shaarli.

I currently have 4319 links, collected over 13 years and 8 days (started with Delicious, then Pinboard).

Link rot and relevance is an issue, and I rarely go back to links that are more than a year old.

I don't delete broken links though, I like to think my Shaarli is a fair representation of my interests over the years.

I recently developed a Shaarli extension for Ulauncher. [0]
