I came across a bookmark website today that you can save and edit your bookmarks easily. Bookmarks are in a table-cell structure with visually drag and drop ability. And there is a chrome extension for bookmarks that you can save your favorite sites with one click.
You can find word lists here under specific categories, I used Wikipedia and Definition.net category pages as a source while compiling this list. Since Wikipedia and Definition.net expanding, this word list will be updated automatically.
