Ask HN: Do you remember what you read on HN? (And if so, why/how?)

I read HN on a regular basis, spending anywhere from 30 minutes to 2 hours reading the articles shared. But I quickly realise that I rarely really remember all of what I read. I typically mentally summarise an article and what I got from it at the end, but often times I can forget it the very next day thanks to the huge influx of new news. What do you typically do? Is this an example of how we can appear to be productive, but are actually just cyberloafing?
