Link Tweet

I am trying to add only a simple Twitter icon that will force the user to share a link to their Twitter account. I see that there are two ways to do this:

• A simple Tweet button on the page. Like at: http://dev.twitter.com/pages/tweet_button

• or, a more complicated way, going through the oauth process and calling the API to update the state of the user. Like in: http://dev.twitter.com/doc/post/statuses/update

It seems to me that if we go with an authenticated process, I really need to register the application with Twitter, whereas if I just used the Tweet button, it’s very easy to insert the necessary tags on your website.

What are the advantages / disadvantages of this or that path? The only thing I have found so far is the speed limit coefficient (150 / hour if not authenticated, 350 / hour if it is authenticated)?
