Well, that's a very good question !
I think that when the script will be online, it will allow us to rank a lot of accounts and then we'll be able to understand better the « meaning » of our own results.
I'll try to put a first version online – very rough – over the week-end.

Hi Denis. Thank you for computing my « twitter authority ». I also suggest coming up with a range and what does it mean. Example, those of us who got 50 and below, does it mean we are twitter authority newbies?

Cheers!

Hello Jan.
Thanks for your nice comment.

About Magpie, I took the time to think about your model and I still think that using the simple follower count to calculate the price is far more logical than using any Authority count.

Or maybe, it should be an option chosen by the advertiser, like (Do you want to be broadcast on accounts with huge numbers of followers or on accounts with huge authority ?)

I'll contact you directly, if you don't mind.

Just tested. You get a 40 ! Congratulations
Anyway I will post a script as soon as possible where people will be able to test their Twitter Authority according to my algo.
It will be fun.

Thanks for sharing this. I wonder how my « twitter authority » will look like based on your formula. Kindly advise.

I’ll try to explain one thing by example you seem to have ignored in your authority algorithm.

Twitterer A has 100 followers. He follows everyone back.
Each of his followers follows 100 different Twitterers and A is one of these.

Twitterer B has 100 followers, too. He follows everyone back.
Each of B’s followers follows only 50 different people.

With your algorithm should the authority of A equal B’s authority.

I would argue that B’s authority is bigger than A’s because the attention of B’s followers isn’t parted that much.

What do you think?

Denis, could I point out my TwitRank project (see link)… it already does what you want and includes authority of followers..

I must have missed the formula somewhere, or at least indications. You don't consider someone who is frequently re-twetted as authoritative, for instance?

Very interesting indeed work, Denis. Thank you!

Are you planning on posting the algorithm so that we can actually look at how your assumptions A-D are implemented?

Also, it would be great if we as a community developed a sort of algorithm which is open and agreed upon by a large number of people/companies. We could then use it in different applications and still share a same common understanding of what we’re talking about.

Obviously, I am referring to Magpie where we need a means to calculate the price of advertising messages. Right now, we use the follower count but are always looking for ways to improve…

Thanks for taking on this discussion.

Interesting, but the average could be easily biased no ? Your options are brilliant !
