Start a website. Publish news on it. Call it a "newspaper".
You need to rent a server that can do streaming audio. Or, you could just make podcasts, and post them on a server.
The hardest part is creating content that people would want to watch. Once you've made each program as a video, compress it down to a suitable size, and post it to YouTube. It it's good enough, then you will get the viewers.

With parsing packages like pyparsing and Antlr it is much easier than it used to be to design a grammar and implement a compiler for a new language.
In some countries it's easy, in others it's very hard. (See here for some detailed figures on "ease of doing business".)
We've been doing that one for quite a while, and what with all the spam we get, it has been seriously suggested that people shouldn't be able to send messages for free.

The ability do do this is designed right into the Internet – you don't need to ask anyone's permission to create an application that uses the raw packet-sending capability of the Internet to communicate between arbitrary Internet-connected computers anywhere in the world. (Technically, this is possible because the Internet is designed as a dumb network.)
The problem with starting a voter-driven links site is that you need a critical mass of users to make it work. When we consider sites like Digg and Reddit, each site has its own collection of users, and its own system of counting votes and ranking stories. To implement a system that lets anyone start a voter-driven popular stories site, we need to separate the collection of voters from the ranking system. In other words, have a voting site within which voters could vote for stories, and then give access to the raw voting data to anyone who wanted to use that data to calculate rankings for new and popular stories.
Currently there isn't any safe, cheap technology that lets you fly anywhere you want to (I can think of helicopters, which are expensive, and microlights, which are dangerous), but at the same time there is no law of physics preventing the eventual development of such a technology. If such a technology did exist, then it would be much easier for people in general to go to remote places that currently they cannot easily visit, and the freedom of exploration that many of us enjoy on the roads would extend to the whole countryside.
