Re: [soa-rm] What is SOA (Really???)

[Rex Brooks <rexb@starbourne.com>]

Thanks, Duane,

Just for the record, this is without doubt the most active TC 
discussion I have ever been involved with, and also has had more 
reference and research materials submitted as well. Considering the 
huge volume of all this in WSRP from its beginnings in January 2002, 
that is really saying something. It is challenge at times, just 
keeping up with the threads. Take a day off and you're half a day 
behind just to read and respond to the email.

I'm not complaining, just pointing out that, under these 
circumstances, even a much less aggressive set of milestones would be 
likely to slide a bit. Frankly, by this time in the lifecycle of a 
TC, I would have expected to see a fall off, and I haven't seen that 
yet. This is all good. But we just need to mindful that sometimes it 
is also helpful to take a step back and ponder for a while, and that 
is what I am doing in response to Martin's post a bit earlier.

I've been through several of these Socratic pursuits, usually along 
the lines of, "Yeah, that's all great but where is the killer app? or 
"Granted, but what is the next big thing?" FWIW. for me, this was the 
next big thing, and it is a lot bigger than the top of iceberg  had 
me believe.  So we also need to bear in mind that just because 
someone is not responding immediately, doesn't necessarily imply 
anything

Thanks again,
Rex
