What is a Blog?

Definition:
blog
A frequent, chronological publication of personal thoughts and Web links.
Information
A blog is often a mixture of what is happening in a person's life and what is happening on the Web, a kind of hybrid diary/guide site, although there are as many unique types of blogs as there are people.
People maintained blogs long before the term was coined, but the trend gained momentum with the introduction of automated published systems, most notably Blogger at blogger.com. Thousands of people use services such as Blogger to simplify and accelerate the publishing process.
Blogs are alternatively called web logs or weblogs. However, "blog" seems less likely to cause confusion, as "web log" can also mean a server's log files.
Synonyms
web log
weblog

As you may have gathered from the previous postings, the present Blog is not so much about 'personal thoughts' as about research related to the study of the works of Philo of Alexandria. As such it will be dealing both with material available on the Internett as well as research published on paper.
To make this WeBlog about Philo more effective, I hope to be able to get some more people interested in joining me in blogging. Stay tuned...:-)
