WOA isn't for the masses

Nick Gall's note on Web Oriented Architecture--basically SOA constrained to RESTful princicples--got me thinking about the futility of end-user programmable services.

Given the difficulty even highly trained engineers have in creating good interfaces, only a select few will be able to take a list of arbitrary services and make anything like the "slightly less general interfaces" mentioned in the note. Of course, that makes it worth it, because even a tiny percentage of the web's population is still significant and can benefit all. We just shouldn't expect the nirvana where ever user is a programmer and creates a wonderful mashup of services.

I suspect instances of "serendipity" and "unexpected reuse" will exist at the services level, but will be far and few between. As far as I can tell, I'm right so far...
