It seems to me that if someone enjoys airing their personal dialogue on the web they are seeking attention in some fashion. It seems so easy to observe that statement as a negative inference, as if seeking attention is far too uncool to do, and that we should seek it in more of a indiscrete fashion. Well that's my opinion on it, at least. It just seems like desperation to observers if someone is trying to hard to get attention. Of course all of this is referring strictly to people's personal blogs. There are blogs that I enjoy reading but usually they are directed towards a particular subject, or a variety of subjects, or speak to a category of people that think similarly. Such include; slate.com, 3quarksdaily.com, and viceland.com.
These website seem to house, attract, and cater to a community of visitors whom all think, vote, dress, and critique life in the same manor. These online communities allow people to keep up with trends, get the most progressive information, and provide entertainment to individuals all sharing the same tastes. In this manor they provide reinforcement for the individual reading and perhaps even act as a "homebase."
