Where to submit my articles?

Do not care about Do Follow or No Follow. Post to both. Important is only if the article you post/website you build gets indexed.
My strategy is to take one of the lists of Article Directories/ Web 2.0 from here and make a test run with high quality spuns on it.
Then I do a little blast to these links. After one month I check which of them are indexed and live.

Then use those for many campaigns...
