nothing specific; all "here's how I used this tool my company makes to do a thing" blog posts on the company site itself are just inherently ads.

I find it disingenuous every time I see it, because (while nothing is done to imply this) it reads, at first, like a genuine blog post someone wrote on a personal site.

we all read enough blog posts every day that the site hosting the blog can easily go unnoticed, and I feel like companies hope that "blog fatigue" will make the post look more spontaneous and genuine than it is.

I often forget that YCombinator is a greenhouse for companies to be fed and watered and pruned so they can become standalone entities out in the wild, and that this means that I'll be presented with blog posts about products from the product-makers themselves.
