http://www.blogyoursite.com/ is a site I created where you can blog about your own website. All links you add and blog about are dofollow. Simply sign up for an account and blog about stuff on your website add links to your pages etc... The site is now a PR3 so your pages should get a quick boost in the search engines. I would love a link back to the site but it's not that big of a deal if you don't. Everyone knows, "What goes around comes around". "Give and it shall be given unto you". ect... Also, there were alot more blogs on there a couple months ago but I allowed people to have too much authority and someone deleted every post on the blog somehow? I couldn't figure out how they did it but I have fixed that problem so hopefully no worries. So, sign up, blog about something, link to it and submit! It's easy to get PR3 links.
A website like that is just asking to be abused. It's probably just a matter of time before that website gets penalized and becomes PR0. It's too difficult to control whether you are linking to bad neighborhoods or not.
I run a pretty tight ship on it and make sure the crap stays out. I get an email for every new post and I check every one. Bad neighborhoods are easy to spot so it's not that hard to keep it clean.
Thanks for this opportunity, I am going to write about your site on my blog. I am also going to write a couple of posts on blogyoursite also.
