I'm... not sure where I was demeaning it that way? I certainly never said the quoted thing, and I didn't intend it.
I don't think that Summly was a bad product, and I don't think D'Aloisio is a bad dev. I specified him alone because as far as I know he's the only one Yahoo acquired - SRI is great but Yahoo didn't acquire their devs or exclusive rights to their tech.
The question at hand is whether Yahoo got their money's worth, and I'm claiming that they didn't bring on enough relevant tech or expertise to justify the expense. That holds even if Summly, SRI, and D'Aloisio are all fantastic.
