I think his point was that if it's in a spreadsheet, it would only take a few minutes to copy the "name" column, excluding all startups where the "launched" column indicates that they're still in stealth.

He wasn't calling using a spreadsheet lazy; he was calling using one and still being unwilling to compile a list of YC startups lazy. Of course, PG is busy enough that I wouldn't blame him anyway (but he does have people working for him to do things like that).
