Link shorteners like bit.ly are great because (a) they let you fit long links into the tiny space allowed for Twitter updates and (b) most services allow you to track clicks on the links, giving you valuable insight into who’s interested in your updates. I wrote about shorteners in a recent infinite42 newsletter.

Until now, you had to go to an external service to do this if you were using Twitter direct – not a huge problem, but every step counts in the social marketing game, so I like this update.  Many Twitter client tools have their own shorteners already, so Twitter is really just filling an obvious gap in their product.

Here’s an interesting question to ask yourself: would you share your bookmarks with a friend? How about 100 friends? How about 1000?

If the answer is no then don’t worry. It doesn’t make you a bad person. There are some good reasons why it can happen so read on…

Social bookmarking sites such as Digg, del.icio.us and stumbleupon allow internet users to vote on their favorite sites. You can even start your own based on Pligg. If these bookmarked sites get lots of votes (or tags, or diggs, or whatever you want to call them) they will make it to the top and get noticed. This is web2.0 in action.

How do you share your bookmarks? It’s very easy to do this. On most of these sites you have a profile page which stores all of the tags that you have created. Sharing or promoting your bookmarks is just a case of sending people to this page with a link.

So what would 100 people think of your bookmarks? Would they think you are a good Digger or a great citizen on StumbleUpon? Are you consistently tagging interesting sites that are relevant to the category that you choose? If so then the answer to the first question should be yes!

If the answer is no, it might be that:

1. You are bookmarking for the sake of it
2. You just Stumble your own stuff to get traffic. If you do, and it’s good stuff, then this seems OK to me. It can look a little self-centered though
3. You are bookmarking to try to raise your profile

Here’s an easier question: if you don’t feel happy sharing all your bookmarks with friends then how about sharing a subset of your bookmarks? Maybe they are tagged with the word “proud”, or “worth sharing”. Many of the bookmarking sites, such as del.icio.us, allow you to use tags.

If you can consistently show that you are finding interesting pages that are relevant to your group of online friends then you will get a good reputation and people will start to look at what you are up to. This leads to more visitors and more traffic to your own sites. That’s a good thing, and means you can say yes to the original question.
