Sometimes I do both.

I've occasionally left short article length comments on other blogs, and then posted an expanded article on the topic on my own blog, and then link to the blog where I left the initial comment. Turns it into a win-win for myself and the other blogger. They get a worthwhile comment plus a link.

Yes, I do that quite often (post a shorter comment on the blog, then a longer post on my own blog). And I've seen it work in reverse (people posting a short comment on their blog, then the full post on their own blog).

I think it's a good strategy for coming up with blogging ideas, and, of course, I'd always backlink to the site where I got the idea from.

Another useful technique is to look for comments on your own blog and see which can be spun into their own post. That way, you're creating internal links within your blog, which is good for SEO, as well as rewarding your interesting commenters by providing a full post response to their comments.

I do the same thing guys. More than one blog post has its origin in a comment. I wrap up the comment and expound on my blog.

inter123, it takes some time to find good blogs. It depends on your niche though. If you are focused on network marketing feel free to stop by my blog (RBs Keys - In My Signature File), plenty of reputable and well-read bloggers comment on my site.

Will I too am like Dan. I will often leave the comment in a very brief and reduced explanation and quickly go and develop the idea into an article. I think that when people read intelligent and helpful posts on blogs, it motivates them to visit your own blog and see what you are all about.
