Excuse me for my bad english, I am French.
I find this discussion about hub very interesting.
I have to questions about this theme :
1.do all search engine take into account the hub in their algorithm? (For my part, I heard altavista was the only)
2.What are the criteria that made a page a good hub?Is it the number of inbound links or the popularity of these links?
Thanks in advance for your help

"Ainsi, les pivots et les autorités sont les types distincts de pages qui montrent une forme normale de la symbiose: un bon pivot se dirige à beaucoup de bonnes autorités, alors qu'une bonne autorité est dirigée à par beaucoup de bons pivots"
Warning - machine translation ;)
If you have not already done so take a look at Structural Analysis of the World Wide Web [w3.org] it will be a good starting point for your research.
An authority page has two features - 1) that the content is good (this is ultimately judged by a human for a core set of authority pages - eg by pinching a few from the ODP) and 2) that several good hub pages link to it.
A hub page has one feature - that it links to several good authority pages.
As can be seen, this is a bit of a circular argument if you consider pages in isolation. However, it really is just a set of several hundred simultaneous equations (bit of revision needed here for the Artists) in several hundred unknowns, and can be solved with matrix methods.
I say 'just a set of several hundred simultaneous equations' but it mustn't be forgotten that a famous aircraft designer of the early twentieth century spent 6 months solving a set of 70 equations in 70 unknowns by hand. The thing could now be done on a PC in the twinkling of an eye. Is the web still the greatest achievement of the electron?
