tip:
when saving ideas for research from the internets, spend the extra few mins copying the text, taking a screenshot, downloading the document, and store it in a database that you own.
don't just store the link.
often I go back to bookmarked tweets or links I saved, and I find them broken because the author deleted them, or doesn't exist anymore or simply disappears from bookmarks.
better to make it permanent than to lose valuable stuff.
