My favorite thing about del.icio.us is that there are lots of things to do with the app without downloading an extension or spending an hour or hundred ;-) with the API writing code. These are my list of very simple things you can do with del.icio.us without needing extra del.icio.us tools.

1. Add del.icio.us to your rss feed. If you have a site or blog on a particular topic, a great way to find ideas for new articles or posts is to go through all of the posts tagged as your topic everyday. Do it quickly, though. Depending on the keyword(s), there may be too many sites to go through easily.
2. Create a Fashion LookBook, like this one by tagging flickr photos as “lookbook” or “to_try”.
3. If you keep up with you favorite bands using del.icio.us, you are going to be suprised at the music you discover by voyering someone else’s music. Use the FtF rule (ahem, the find the first rule). Come on, you know you do it! Find the First del.icio.us user to tag a site/band/artist you like and see what kind of crazy music links they are savin’!
4. Take some time to actually go back through and review all of your del.icio.us bookmarks. Which bookmarks have been the most useful to you? Are they particular articles or posts or links to home pages or large site?
5. Share links with study buddies, students, coworkers, family… you know, like people you know in real life. For example, here are my math links. If I were in a math class right now, I might share this page with group project members or someone I was tutoring.
6. Tag sites that you use in creating a presentation with a single tag (e.g. “some_presentation”). With that tag, you now have an instant resource for remembering how you pulled the presenation together and a bibliography.
7. Make your own del.icio.us vocabulary. Don’t want the world to know you think some site totally sucks? Mark it as “~g” or whatever. Pick some characters and make them mean something.
8. Find things quickly away from home. Need your favorite pumpkin pie recipe when baking at your mother’s house? If you have bookmarked on del.icio.us, you don’t have to google pumpkin pie and then search through all of the recipes to find the one that uses brown sugar. And no, this particular recipe does not show up on the first page when you google pumpkin pie brown sugar.
9. Did you leave your ipod at home? Look for music that has been bookmarked.
10. Tag Liberally… it feels good. As you might have guessed, I tag liberally (as in at least 5 tags per post) because you never know what weird kinds of things you are going to be looking for in the future. For me, as well, it is a way of being more articulate about the reasons I am marking the site.
11. Bring you obsessions into your consciousness. What tags are you using the most? Are you surpised? You can find out which tags you are using the most by selecting sort by freq. in the tag options on your main del.cio.us account page. Ok, so what you bookmark doesn’t capture what you put your time into, but they do give you a general idea of the sites you think you will need in the future.

Sample lists, comments and tasks on del.icio.us

• to_research
• put_on_adgenda
• email_to_phil (because he is so uncool and doesn’t have a del.icio.us account—I do not want to imply that people who do not have del.icio.us accounts are uncool, rather I am just trying to get Phil to get an account!)
• don’t_forget

If you maintain two separate del.icio.us accounts (one personal account and one for a business or web site), you know how difficult del.icio.us can be to use if you are having to switch usernames all of the time. Essentially, everytime you want to post a site to the other del.icio.us account you have to logoff, and enter your other username and password.

But you aren’t supposed to use del.icio.us like that. Just create one account and tag personal stuff as personal and business/site stuff as business.

I think there are some good reasons for having separate del.icio.us accounts. For example, if your del.icio.us links are recommendations to your users/readers, you might not want them to think you are endorsing all of the crazy sites you post to your personal account. No matter whether or not your reasons for having two del.icio.us accounts are ‘good’ reasons, maintaining two accounts is cumbersome if you don’t have some good tools. To overcome the nuisance of re-logging into del.icio.us all of the time, I have devised this simple “hack” (if you will). Ok, so it’s not really a hack, but let’s just pretend.

• del.icio.us buttons provided by del.icio.us
• del.icio.us complete extension from the Firefox Addons page

The idea is that you will remain logged in under one user, so that you can post to that account with the browser buttons provided by del.icio.us. The browser buttons provided by del.icio.us will always post to the account you are currently logged in under. So, if you log out of the del.icio.us account that you have set up with the del.icio.us browser buttons provided by del.icio.us, you need to log back in in order to post sites to that account.

Using the Options…/ Accounts tab in del.icio.us complete, set the second button to post to your other account. Voila!
