I tried to contribute to this thread but my IP seems to have been blocked after submitting my comment. I included a list of 6 Chrome extensions and their URL that in my opinion improve the usability and features of HN. I'm afraid to submit it again since I don't want the current Squid proxy's IP being blocked also and then I won't be able to read HN until I find a different IP I can route through. Anyone know how long IP blocks last?
