Best Professional Association for "Cybrarians"

[Kieran Roe]

I am a librarian who is new to my Information Technology Specialist
role.
I will be responsible for training internet users and providing
assistance with information technologies (both hardware and software) to
a network of special medical libraries.  I will also be involved with
web page design.

With the ability to join but one of the major library associations, I
would like to choose the "best" of these national associations for the
purposes of networking and professional development in info technology.

I find the kind of discussions that take place on this mailing list to
be quite relevant and educational.  So I am curious -- which of the
professional library associations have the members of this list found
most useful for their professional development as information
technologists?

ALA, SLA and MLA each have information technology sections.  Are there
important differences in their focuses (beyond the obvious distinctions
among library types)?  The Internet Library Association
(http://www-org.usm.edu/~ila/) looks to fill a very useful niche! 
However, I would also like to join the info technology division of one
of the established national associations.

Where do you belong and why?

Many thanks for your assistance!
