(Probably skip if you don't want to read a ~rant..) Questions: - New "format"? It is a CSV with spaces as separators and no header? Why? - Global file located in the home directory? Why would you want another file to pollute the $HOME? Why not just $BOOKMARKS_FILE or something? - Local bookmarks file - why don't just reuse README.md? Add 'Resources' section and chuck markdown links in it, parsing that is not (much) harder, and you get nothing more with a separate 'bookmarks.txt' file. As some other comments pointed out, there are no tags, no (semantic) grouping, no content archiving, etc... This is just a list of URL with optional title attached to them, this is not a distinct 'concept'...

The format itself is not as useful as the unix-like shell oneliners one crafts around it. The inflexible simplicity is therefore the point. (and also it's easy to modify manually)
