Sometimes I'm using yahoo site explorer for this. When you find one good blog where the comments are doffolow, find someone who has comment on that blog and track him with the yahoo site explorer.
There are lots of software in the market for searching blog commenting you can try blog commenting demon and for free tool you can use commentkahuna.com
You absolutely right. I started not long ago and with all my questions I am first of all checking forums. Usually I am finding all necessary information. Thanks people!!
There is also another way. If you chose an identity that no-one is using on the net and blog interesting things, people will still come to your website i.e they will search for it. You will see this in your stats. For example, I will look for stats increase in the term "whoisbid"
It's a waste of time. No genuine blogger accepts link spam and you would be daft to pay to get onto a site that does. If you have to stop and check to see if a blog is do follow or not you are in the wrong place. Your time is valuable.
Most blogs are no follow because of all the bad advice one gets from people who have got nothing to contribute other than greed and self interest. That does not work on the web. Long term you have to find the balance between your personal interests and those of a much wider community. Blog commenting in no shape or form is a link building tool. Yes you can get links from blogs which don't flag your contribution as meaningless spam, which are still do follow but that is not why you want to be commenting. Try to understand that if your sole purpose is to find do follow blogs then those that you want will either flag you as unwanted or they will eventually go no follow. The rest will simply fall over and die once they have exhausted their purpose. So why waste your time chasing a pot of gold at the end of the rainbow? Because someone else said so? You are not that daft surely. What we need are spam free resources. What we need is an attitude. What we need to do is to take responsibility and try to understand that we are all planting seeds.
I prefer my own dofollow search engine which I built on http://www.seo-traffic-guide.de - it is free to use for anyone and does not have any results limitations...
There are tons of blogs out there listing do-follow blogs list. you can google it. I also find some forum posts here.
