When I think about netscape, I think about the terrible way,
how it handles newsgroups....
...when doing a resort of the newsgroup-entries it's extremely slow.

Maybe it again checks data on the newsserver again and again.

And when I think about Netscape, I se that it reloads data via network,
when you want to save it, even if it' already on the screen.

So, theese things are the reason, why I don't see why this algorithm
is something special, until I have seen that it really is fast. ;-)

I have thought a while about the threading, and thought I have some good ideas.
A while later, I saw, there already is a datastructure that is useful
for threading, and it is the Tries-datastructure:
  http://www.csse.monash.edu.au/~lloyd/tildeAlgDS/Tree/Trie/

If you use the message ID's instead of the char's of a word,
then this datastructure is well suited for news-/mail-threading, I think.


So, other people already had done, what can be used here.

But maybe thze algorithm you show on your pages is really good.

But I would trust your algorithms more than algorithms of
netscape-programmers ;-)
But maybe it's really good and only the overall-design of Netscape was bad. ;-)
