Or maybe you've just been "doing things that don't scale" until it has no longer scaled, and now it's time to bring in some fresh blood to help share the load.
I'm sure that having somebody on payroll to help companies get in front of HN would be easy to justify in the budget. :)
It's not super sexy because it's not an automated solution, but sometimes automation just isn't the right answer.
It might save everyone a lot of time/effort. (Or I could be wrong)
Quick thought: What happens if you only minimally edit the posts, but instead brand them as "sponsored?" Maybe even tweak the colors on the sponsored posts?
Perhaps start each post with some kind of boilerplate disclaimer. Something like, "Hacker News is sponsored by YCombinator. Every YCombinator startup gets an opportunity to have a 'Launch HN' post. Today, Hacker News is brought to you by..."
(And then timebox your editing to XX minutes / company.)
People come here for interesting things to read. The point of the editing is to make the Launch HN texts interesting rather than annoying*. Adding disclaimers wouldn't make ad copy less annoying, so I doubt it would help. It's a clever idea though.
* though a lot of commenters are saying they're too long ("longwinded" and "bedtime story" are two terms sticking in my mind)...maybe we've been trying too hard.
Why not hire writers/editors to do it? Although you are currently doing a fantastic job at this, your limited time may be better spent training a team of paid editors rather than doing the editing yourself?
However, it would still leave open the problem of editing work, which is currently unsolved. I'm hoping that the Meet the Batch threads will involve much less of that per startup. Letting the startups present themselves unfiltered to HN is a really bad idea, because most founders don't understand the culture here and naively step into HN the same way they would, say, ProductHunt—or worse, repeat their Demo Day pitch. This is a very efficient way to get yourself flagged and flamed, and also is a risk for YC (imagine "I don't understand how YC can possibly fund such #@!&*" comments x 1000).
We explain the difference clearly enough at https://news.ycombinator.com/yli.html, but an explanation isn't enough. It needs collaborative work in practice. Personally I think not sounding like an ad and speaking as a person rather than a brand is good practice throughout life, not just Launch HNs, but I'll settle for getting Launch HNs right; that's turns out to be hard enough.
