I'm interested in putting a web blog on my site for use by myself and possibly a few friends. Does anyone know of a program that could be used that would allow the creation of multiple web blogs that could interact with one another; possibly like livejournal?

You can run the same software that LJ uses on your own server, but some people find it a bit complicated to setup.

Take a look:

Another popular blog software package is called "WordPress".

Take a look:

I'm using this one:
http://www.plogworld.org/

Im actully in the middle of programming my own php webblog that will be availible for download once i finish my site, and get the graphics finished for it until then i also recommend PlogWorld :)

I use b2 from http://cafelog.com/.

there could be some Source Forge projects out there tooo

Just use blogger. That's what I do for my site. Pick any template, copy the actual Blogger code, and imbed the code into your design.

wordpress is good. :)

my favorite blog software is movabletype...its got all kinds of cool extensions.

Yea, def. hands down moveabletype

Moveabletype can be a resource hog through. If you end up with too many comments, rebuilding can take quite long and actually interfere with other peoples hosting in a shared hosting environment. I've known many people who hosted with TotalChoiceHosting and had their sites shut down until they either removed the comment system, or found a way to streamline their current site.
