What are Web 2.0 Properties and Tiers?

For link wheeling or link pushing (as I just learned here)... do the web 2.0 properties need to be my own domains/websites? Also, if someone can answer my question below, if not, the short version of it --> with article marketing, do I submit one unique article to a single directory and then link to that directory from other directories and interlink between the other directories themselves? Is that how it works? OR do I need my own web 2.0 properties linking amongst each other? I'm EXTREMELY confused.

"I'm thinking about building link wheels for my site so I can get some PR juice for my keywords but would love some advice on how exactly to do that. This is what I get so far from reading posts here and other places:

-- Write article linking to your $ site with keywords as anchor text
-- Submit that article to high PR directorie(s)/site(s)/blog(s)/forum(s)
-- Ping all those links
-- Create many spun versions of the same article and submit to DIFFERENT directories/sites/blogs/forums
-- Link to the article with the $ making site anchor text in the spun articles but also link between the sites you submitted the spun versions to

Now, does that sound right or am I headed in the completely wrong direction? Anyone care to offer some guidance, it would be much appreciated!"

search for seo blueprint and read cash202's thread. You will learn a lot from it.

EDIT: and when you have read it..........read it again.

I read the thread, very informative but it doesn't answer my basic question. Do we PING the websites that we've submitted the articles to afterwards or let Google index them naturally?
