Thank you. It’s infuriating to use Twitter as an unauthenticated user these days. If you scroll down far enough you get the uncloseable login gateway pop up, and I can never tell if it’s triggered by reaching the end of a thread, or after X posts in a thread.
Here's a trick to read the bird site without logging in - whenever that pops up, pick your choice of "Log in" or "Sign up" (I prefer the latter, I like to imagine it helps to scramble someone's analytics) then click the 'X' in the corner, and the popup goes away for a while.
Some popular sites have alternative interfaces, e.g. Twitter → Nitter. They are a much better user experience if you just want to lurk. Configure your browser to automatically redirect:
Most or all have numerous hosts and you can pick the one(s) that are most convenient or memorable to you. It's also possible to host these yourself, and I've suggested in the past that HN might consider doing so for Twitter specifically. Reddit possibly as well. (The others are fairly low-traffic on HN.)
