[GSG-announce] open house invitation and new blog

[Michael Ossmann]

You are invited to the Great Scott Gadgets open house!  For more
information, see:

This happens to be the second post on a new blog on the GSG home page.
Going forward, we'll post our news there in addition to this mailing
list.  The mailing list will have less traffic than the blog and will
only be used for significant announcements (as it has been used in the
past).  The blog will have the same announcements but will also include
more frequent posts including things like free stuff shipments and
technical content.
