In late 2013, Google blanket penalized Tumblr - coincidentally it's their main competitor web 2.0....funny, wouldn't you say? I think it's a trend.
So as long as you're using Google web 2.0's you'll be fine : blogspot, even youtube videos if you use the content area.
Guys , please don't use any comments , I have just used that and my all keywords from page 1 and 2 jump to 8,9and 10+ pages . really bad. don't know how to recover from them . any suggestions ?
Do web 2.0s work solely for ranking a website to the first page on Google. No, unless your competition was so low it
was barely worth it. However web 2.0 pages can be an excellent way to build a nice tier to your money site with great
content on them that could convert the readers.

i feel that few web 2.0 are penalised and making links on really hurts serp.. i just feel in this way. i am researching and will get back shortly.
also indexing is an big issue. even with good article (unique) and images and perfectly looking ones.

True that, and if you use those popular web 2.0 with good readable content that suits fine to your niche readersi used pretty common web 2.0s.. wordpress, tumblr, squidoo etc etc.
ok , here is a suggestion.
build good quality web2.0 then add bookmarks + social signal+ some high pr blog comments.
wait for web2.0 to rank in top 50 (for short tail) top 30 (for long tails) top 100 (for main keywords)
+ get 200+ web2.0 links to each tier 1 web2.0 . http://www.blackhatworld.com/blackhat-seo/seo-link-building/644625-blcwebs-com-ultimate-private-blog-network-authority-web-2-0-network-links-services.html

They do still work but they have to be used in smarter ways.
