I've been using a service called Evernote. It's basically a big notebook. A notebook that can keep audio messages, web clippings, pictures, handwriting, and text. It is also searchable. You can search any item you have saved including pictures. Evernote is able to find text in pictures and in handwriting, which is fairly effective.
It allows you to import your delicious links and will categorize and save them too. It imports all your tags and makes them searchable too. The service is free, but they put a limit on the amount of data you can upload each month. This is not too much of a hinderance for most everyday users. There is a pay option available.
You can also download programs to use on your computer. This program will sync with your Evernote account. That means that you have access to your note even when not connected, the notes will sync the next time you connect to the internet.
This service is a great way to keep your notes, information, website, and pictures organized!
