One thing I noticed is that the search feature on there is far worse than HN's. Doing a side by side comparison, I have to go to the 2nd or 3rd page on Lobste.rs to get the results that I would have expected to be first.
One of the nice things about HN is that people with way more experience than you in any given field make posts and comments about their work at times. While generally not useful for specific step-by-step instructions, there are good tips here and there that are at least worth considering, or alt viewpoints that may be interesting to consider in the future.
