Google doesn't index links even from big authority sites?

I've been having a lot of trouble lately with indexing.

Some links don't want to get indexed in anyway even if they come from high quality places and have genuine content.

My web2.0's don't want to get indexed either...

Anyone having the same problem?

I think it happening because of the google update.

Indexing is slow because of google updates

Google updates are coming again and again... I think this is the reason big quality links are not indexed..

web 2.0s are far away from being treated as links from high authority sites, more likely like new websites (even worse),
having a link from a high authority website does matter depends on the type of link, profile, web 2.0s, comments and such types of links do have much less value most of the time

when it comes to indexing, it's true that things are being really tough recently, especially while using indexing services,
you'll simply need better quality links to get them easily indexed nowadays, the old trash links would require some pushing which is not really worth it
