"Everyone loves open source software. After all… its free! Many times I’ve heard the question, “what is the most popular open source application of all time?” I decided to find out.
"So, I used metrics gathered from SourceForge.net to compile this list. I think the results show some interesting things computer users the world over. Here they are along with the total number of downloads for each one. Enjoy.
"1. eMule – 520,970,337 downloads: The most popular open source download of all time is a peer-to-peer file sharing client. What does this tell you?
"2. Vuze (formerly Azureus) – 489,705,154 downloads: The second most popular open source download of all time is a Java-based BitTorrent client. Wow!"
