Rank only with web 2.0 / selfhosted properties

For keywords that aren't overly competitive (say 1-5000 searches a month) is it possible to rank them with only web 2.0 properties and selfhosted websites? (no article directories, comments, social bookmarks, rss, profiles etc)
I know diversity is good but lets assume you only use your own websites for links and nothing else...

It's possible but depends on how interlinked each of those web 2.0 pages you create is with the rest of the site.

Some web 2.0s are automatically interlinked into the rest of the site, eg. your new page / site will automatically get linked in the site directory of that particular free blog host, or you might be able to tag your posts and then the tag listings get spidered etc, leading to considerable trickle down of link juice to your own pages. You can use these types of web 2.0s to crank link juice to your money sites and rank for low competition keywords.

However, on other web 2.0s, your new stuff is basically like a little island and it doesn't get much or any link juice from the rest of the site. These aren't so good for funneling link juice (because they don't have any to send) and you won't have much luck using them to try to rank without more external backlinks.

btw zeano you need to start hitting that thanks button buddy! Pretty bad etiquette when you're asking noob questions with 0 thanks... you will get more answers if you start thanking people.

I would build links to those properties - so if I ever drop the money website (because keyword is not that great after all) I wouldn't lose all built links.
I'm wondering about personal experience of other people - if someone here only use their own websites for backlinks.

Eh, I usually don't remember about stuff like that.

But is it a good etiquette to demand rep?

Actually, Autumn was telling YOU what good etiquette is as a favor to you.

I saw no demand for rep but I did see a member telling you that when you are helped that you should take 1/2 second and hit the thanks button.

Don't hit it for me, I'm just sharing what you missed in Autumn's post.

It's not only possible to do that but better.

Anyone else wants to share their experience?

Everyone say you should have diverse links because... I don't know, since it looks more natural? But it's not like owners of cnn.com (authority website) go around creating forum profiles, comments or articles for ezinearticles etc. They have links from blogs and websites plus maybe social bookmarks (popular services not some pr0 pligg).
I guess the only problem is to properly backlink and build PR of your own websites/blogs.
