From the time that blogging started out, it really has come a long, long way. At first it was such a niche format, that one had to constantly explain to people what it was. I remember doing that when I started out blogging in 2004. There were so few blogs and many of them were rather technical and IT related. The interesting changes that have happened to blogging over the years is that they have become mainstream and that has led to a vast variety of blogs being written. The bulk of blogs now are personal blogs, where one can share one's thoughts and feelings.
I came across a site called Thoughts.com that offers users a free blog based on exactly this topic. A place to share thoughts and take part in social conversations, a place to interact with a larger community, and a place where one can automatically be updated on one's friends latest posts. You might say that a lot of other sites offer the same thing, but I think the difference here is that they have a lot more control over what information you want or don't want, which is really the key.
So along with the regular posts, there is also a section for users to post breaking news stories and where one can participate in discussions. It's a bit of a combination of blogging, social media sites and viral videos as well. I found their "one love policy" of being respectful to others very nice, since a lot of people find it a great joy to be rude to others while hiding under the anonymous tag.
