While I'm not interested in pursuing any of those I appreciate thinkers out there that push their ideas live.

Would up vote this 5 times over some bit coin lulsecz space station news... Keep em coming!

Agreed. Only one of these ideas has financial potential, and even then it's not an easy market to tap for that particular service.

Still, it's nice to see some idea flow as it always gets the juices flowing.

1. Nice idea, maybe I should built this into "I Write Like" (BTW, it still works: http://iwl.me) ;-)

An interesting change might be to allow it to scrape tumblr for a user's text. That might make it even more viral.

I remember it going viral! Curious to find out how it's doing now in terms of traffic.

Now it's down to about 1500 to 4000 visitors per day. As you can see here: http://i.imgur.com/V5xMr.png the viral effect lasted for about a month.

Nice to see that people are still visting it! Is most of the traffic direct or from search engines?

Yes, that was the one I was thinking about. Apparently I write like Cory Doctorow :) Added link.

It said I write like Cory Doctorow too. Hey ...

That made my day, apparently I write like William Gibson!

About the idea 4 (World map live postcard). I made something similar here: http://iambored.wreally.com/

It's a real time map showing who is currently viewing that page (you need HTML5 geolocation api). However it never took off because for it to be fun you need to get a bunch of people on it at the same time.

May I suggest the view starts out with the entire globe? It zoomed in for me, and had to intuitively know to press the + key to zoom out where I saw a couple of others. If you had clearer zoom controls and a more visible icon for each user it would be more interesting. Posting something like this to google+ right now could generate a huge number of people checking it out.

Thanks for your suggestion! There is a snag in Google maps which causes grey areas to start appearing outside the boundaries of the world map (on top and bottom). Which kinda sucks because it makes the map look ugly. That's why I had to set it in this zoom size. But what you said completely makes sense. I am going to go ahead and change it to a lower zoom.

Does anybody know if there's already something like the world map radio? Can't find anything on google.

The world map in realtime is interesting. The iphone app Beluga does this (they got bought by FB) sorta, but in reverse. They focus on the chat, and have the ability to see a map of where everyone is located.

It's pretty slick.

About Idea 2, Streema (http://streema.com/radios) offers a curated set of stations from around the world although not plotted on a map.

Thought #6 was neat and I was bored so I created http://www.namestofaces.com
