Well, the biggest problems with the internet seems to be the World Wide Web. NNTP has improved (some of these improvements at my suggestions, such as support for 63-bit article numbers), and Gopher has also improved since the original specification (now there are "i" type lines in menus, which are useful), but WWW has just gotten worse (and that includes Hacker News to some degree too, but not as much as Google and Facebook and so on). I have set up not only HTTP but also NNTP, Gopher, QOTD, SMTP, etc, and may later also set up IRC, Telnet, Viewdata, etc. Additionally, many things I serve on the HTTP are just direct downloads anyways; no need to deal with 100 megabyte files just to access a text file or other file that you wanted to download. And, you can do it too, if you want to do, I suppose.
