Web 2.0 deindexed for no reason !

I am new to building web 2.0s. I have built a beautiful web 2.0s with images, about us and contact page and 3 posts of about 350 words - all original, manually created. Then I have built a twitter and pinterest account and shared those 3 posts there too. Then I've created 2 quora links out of which one got removed by the moderators. I have accessed my web 2.0s from firefox but also checked it on my google chrome whith browsing history not deleted. I did not link to my moneysite from it.

After 3 weeks, one post of my web 2.0 got indexed. When searching for "site:myweb2.0.wordpress.com", only that post came up.

Now, after 1-2 more weeks, nothing appears when I search that. It's not on google anymore. Also, it does not say "register this property at webmasters bla bla bla" like it normally does. Now it just says that "no results got found".

Did my beautiful web 2.0 got deindexed ? If so, why ?

Just wait for a day or more. Probably it's just a Google dance.

Google dance ? Is being indexed or non-indexed a matter of google dance too ?

I have seen problems with homepages on web 2s while individual posts are indexed. No matter what I do the homepages do not update.

Don't disavow links in the period that it is unindexed. It will come back up. The algorithm is testing whether you freak out.
