For this reason, some people prefer mailing lists for their daily reading and vice versa. Mailing lists can also be created and destroyed at need, while usenet groups are difficult to create, and once created, stick around forever. With some exceptions, individual software projects will do their development on a mailing list rather than a newsgroup.
Mailing lists are notoriously hard to track down.
Here are a few good ones to get you started with the hard-core issues of Linux and free software development. This is the development list for the Linux kernel. This is where Linus Torvalds, Alan Cox, David Miller and the rest of the kernel developers hash out the internals of the kernel. Beware, this is an extremely high traffic list, sometimes producing 7 or 8 megabytes of email each week. Whenever a new license comes up that wants to be or claims to be Open Source, this list discusses it.
