When, say, every ISP in the world is bouncing half of its BGP links every time
they come up because vendor A's bug aggravates vendor B's bug, it's helpful to
know what the problem is.  You might have encountered this in your own lab, or
magically figured it out before the thousands of others on NANOG seeing the same
problem, but odds are you won't.

If vendor information is relevant to the discussion, it has merit.  Vendor
information purely for marketing or bashing is not; this is long established on
NANOG and seems to work well.

Wah.  If you choose to use unpopular hardware, that's your choice.  Cisco and
Juniper account for around 98% of the Internet, so don't pretend you can ignore
the implications of that.

NANOG is a lot of people's link to the "community".

That's funny, I remember a *lot* of vendor names being mentioned during the WTC
attack and subsequent complications.  Maybe not equipment vendors, but certainly
service vendors.  There was a lot learned there, and if you ignore who was
helping who and which vendors did the learning, you're going to be behind the
next time it happens.

Press releases are marketing, and thus are not appropriate for NANOG.  If
someone wants to provide on-topic technical input, that should be welcome
regardless of which ISP/vendor/etc they work for, or whether they hide their
affiliation behind yahoo/hotmail.

Do you really think the equipment/circuit/service vendors you choose do not
affect how you design your network or the resultant services and availability
you deliver to your customers?

As Randy says, I encourage all of my competitors to think that way.

Ethernet isn't a terribly difficult concept.

Ethernet is just another tool in the box.  It has its uses, just like T1's,
SONET, ATM, and even Token Ring.  Perhaps it's more useful today than it was
yesterday; we'll undoubtedly have a shiny new toy tomorrow though.

No.  You haven't dealt much with STP if you think this is a good idea.

You'd be hard pressed to find any ISP world-wide that didn't use Ethernet.

Just about every ISP uses other vendors.  Your point?

Ethernet is _a_ technology.  It's not the only one, and it never will be.
