thx bro for the answer, i will try what you suggesti sugest, info blog for tier 1, web 2.0 for tier 2, than another web 2.0,profile, comment ,etc for tier 3
thanks a lot mateAlthough I wouldn't suggest web 2.0 in tier 1.
However, if you are using that in tier 1; you can still use web 2.0s for tier 2 as well.
Make sure that the content used for tier 1 is good quality. And the accounts used for both tiers are different.
