Thanks! I have not used shaarli and bookmark-archiver personally. But from their documentation it looks like shaarli doesn't archive in various formats and doesn't have auto-tagging feature. About bookmark-archiver, I think one can't add links into it directly via web-interface and doesn't organize links directory-wise apart from features like auto-tagging and summarization. I'll look into alternative bookmark managers, and will try to provide some comparison chart in README.
