I tried Evernote, Ubernote, Google Notebooks etc. Adding pictures and easy export were the most essential features for me. Finally, I created a private blog (Wordpress or Blogger would do) and it has everything I need. Easy editing, XML export, pictures, video.
BTW, if you bookmark sites to keep the text for later, it's not a good idea. The link may change, the site may get down. Better copy the whole text to your notes storage, it will always be accessible and searchable.
