You can list your interests on your Blogger profile. This allows others with the same interests to find you. In addition to blogging, I am really interest in Google AdSense. There were 163 other people on Blogger who listed that as a keyword in their interest. I visited each and every one of these users. I also checked out all their blogs. This was a monumental tasks since some of the bloggers had 20 or 30 blogs each.
One common pattern I found was that there are a lot of blogs that are light on content. By this I mean the blog has exactly 1 post which is only 1 paragraph long. Perhaps I can understand this. I created a test Blogger account once and old added one blog post. But I did not enter in a lot of interest in that Blogger user profile.
There was another interesting thing I found on quite a few blogs. Many blogs were hosting Google AdSense ads. But some of them had their pages arranged so these ads had the label "Ads by G". The rest of the label got cut off (it should say Ads by Google). I am not sure if this was intentional on the part of the blogger. I have found that when choosing a wide ad that will just not fit on my web page, the resulting text will often get clipped. I emailed some of these blog authors to ask whether this was an intentional move or not. We shall see what they say.
P.S. Blogger is marking the word "bloggers" as a misspelling. LOL.
