I don't know why you set the MTU to a lower value... What I do know, is that I've set it to 65535; my machine now transmits 64KB instead of just 1.5KB (per packet)... Can you imagine what would happen if I set this to UInt32.MaxValue...?
2. "Show HN" shouldn't be a place to introduce startups and other "real world" projects.
Let's face it, a typical HN user is a programmer wanting to read something technical.
He will not take time to understand/appreciate your non-technical startup. What you can get at most is a snarky comment, but almost all will just ignore it.
This is somewhat annoying. If you have a page with 5 or more interesting links and then after some minutes want to continue, it breaks the xp on ycombinator entirely. I usually leave the page. Why in any hell don't you even just link to the start (or include the header bar)?
I bet it's because of caching the query, to avoid post sliding over page indexes after time, or whatever you thought with that non-session and non-user token. But. It. Is. Somewhat annoying, to cut the ?x=whatever just to return to news.ycombinator.com.
Use a timestamp to refresh the query or go back to use old school bad page indexes, but please fix something, at least the error message. Please!
Is that news? For how long now do they "suggest friends on that picture"? I'm off facebook now for at least one and a half years, even before they "deactivated" (made it invisible) for EU users. Anyone thought there are facebook moderators suggesting friends in just milliseconds while uploading? I personally was shocked it suggested me standing aside in the far background - I didn't recognize myself that fast!
For basically everything TCP is used. UDP is just used by DNS and they usually weight 100 - 200 bytes.
Look into your wireshark!
