You could think of lot's of reasons why people make a good p2p software for free.
As an investment for something in the future,
To show programming skills,(like the old XoloX team)
It could even be that it was made out of idealism or hobby.
Not everything you do has to be translated into money.:)

true raaf.

I'am just curious.

Me too, who can hire several programmers and not pay them?
There is no way that one guy is doing all this even if he doesn't sleep and if he says so he's lying.

He's not doing anything that LimeWire can't do, or has already done.

Truth be told, Shareaza is only a fraction of the existing, leading Gnutella servents, if you consider that stability and relatively low number of bugs is a feature.

Besides, a significant portion of LimeWire's efforts go into innovating - Shareaza does not provide any unique features or protocol enhancements.

This is not necessarily a bad thing, but lets not fool ourselves into thinking that Shareaza is somehow better than LimeWire.

I don't think you should try to talk ppl out of shareaza vinnie;).But it does have some features ppl have been wanting but I like Limewire better :) And some ppl also don't like java.so we let them decide

Let me clarify, I was comparing the TEAM at limewire with the suposed ONE GUY at shareaza.
And I agree that shareaza has just about the same features as limewire, but how was that done without a whole team in less than a few months?
Something smells fishy.

How did you know that Shareaza was created in "Just a few months"?

I think the unregistered does not know it, it's a guess. I would like to know it, who knows more, who got some answers?

From what I have heard through others, its got a ton of bugs.

Don't forget that a significant fraction of LimeWire's energies go into measuring various parameters about the network.

I just had the pleasure of returning from a visit to LimeWire in New York - they have a rigorous testing procedure that they go through for every release.

They also write small programs to capture and analyze various pieces of information about the network. The latest conclusion, is that the burden of query traffic has caused a slow reduction in the number of search results to a typical query over the last several months.

Some people like to watch history pass them by.
One minute your stats are correct, the next minute the RIAA is calling ISPs and your stats mean nothing.
What a waste of time.
