Blog vs. Listserv

The question has come up:  What's the difference between content you'll be posting to the blog versus content you put on the SJRLC listserv? 

Here are what I see as a few differences:

1. The listserv is, and will continue to be, the main avenue for communicating timely information.  Email gets your attention quickly. 
2. The listserv exists not only as a way for SJRLC to communicate with you, but for you to communicate with each other.  Listserv content is generated by all of us.  The blog content will be generated by SJRLC--certainly with the hope that it will spark conversations by way of comments and cross-linking, but blog authorship is centralized, while listserv authorship is distributed.
3. The blog will be more informal than the listserv, which is not to say it will be unprofessional.  The listserv is business wear, the blog is casual Fridays.
4. Nobody wants too much email, so we try to keep the listserv low-volume, high quality.  Since the blog content is "pulled" by you rather than "pushed" by us, we can be more liberal in sharing content.  For instance, we may blog about a cool presentation on customer service, or an interesting blog post, that is not exactly library-related or a cool website on wikis.  All good stuff!  But not the kind of information we've traditionally shared on the listserv. 
5. The blog is archived, categorized, and searchable, which makes it (hopefully) a continually growing repository of goodies.  Listserv postings are more ephemeral. 
6. Last, but not least, is this:  We're not exactly sure how the blog will be different from the listserv.  That's part of the learning, and the answer to the question rests as much with you as it does with us.  Will you subscribe to the blog?  Will  you read it regularly?  Will you link to posts on your staff blogs?  Will you comment on posts?  Ultimately, we're creating this together.  I look forward to seeing what develops.  :-)
