My thinking is that if you can create good content then put the lot on one site. If the content is excellent the links will evolve nicely.

Making life complicated for yourself, or attempting to anticipate what google might or might not do in the future - or even what they have done in the past is not a lot more than a guessing game, you will always be be lagging behind.

Evolve your inbound link building from other site that match your topic. Spend your efforts on creating the content. Save the expense of creating extra sites. . It really is not worth the trouble . . . The pages you create are where the true value is, search engines and people alike eventually work that out, to be realistic If all that content is in one single place. . Google will appreciate it far better than running it around in circles. Users will find it faster.

I think in 2008 you do not need too many front doors.
You merely need to put up a single door that people want to get to (that's not easy) This is why site builders avoid it and create little tricks, little gateways . . . It does not work.

Better to aim for one person. the company's customer . . .
