Hundreds of pages of content are ready to be used. There are message boards and forums set up on a variety of subjects; photography, finance, energy, travel, Windows, DOS, and so on.
As for programs like Net-Tamer, Arachne, and Lynx, they still don't really solve the problem. Many websites are inaccessible, some computers will easily freeze up, and speed on a 286 or 386 is rather slow. Even a Pentium III with Windows 95 and IE 5.5 or Opera is unable to access more and more sites (not compatible with this browser, requires FlashPlayer, etc), with many of them quite slow on dial-up. Last I tried, it wasn't even possible to read the e-mail addresses on CraigsList in Lynx.
The AEIN also saves time because you don't have to log into different parts of it or keep track of dozens of different usernames/passwords. No hassles with "Captcha" codes, pages that don't fit on your screen properly, forms that don't work with your browser, etc.
But this isn't the only reason why. The AEIN is to be funded with subscription revenues so that it is not dependent upon advertisers, as most of the Web is. A lot of ad-based sites are running into financial problems and considering subscription-based revenue models; if this catches on, people will have to pay separate subscriptions to use different individual sites, an approach also likely to fail. The current ad-based, bandwidth-intensive model of the Web isn't sustainable.
Another benefit of the AEIN system is that people will use it more responsibly. When individuals pay for membership and have the same username throughout all of the classifieds and message boards, they are less likely to misuse it. This forum doesn't have such problems, but there are certainly many message boards and Yahoo! Groups overrun by spam and offensive messages.
Yeah, LSPPP is definitely the best modem packet driver I've found
