What to focus improving in order to increase user numbers?

I don’t understand the server you mentioned.

I agree on a modern browser. Web+ is cool and there are Falkon, Otter and Netsurf.
Here is a even more complete list:

But we need Javascript and that’s still missing afaik. [Edit: At least Web+ crashes when stumbling over certain JS sites. And yes, it is already reported.] HTML5 is already in Web+ I think.

I think email is important, too. Good thing is: We already have two good email programs. One simple [Mail] and one advanced [Beam].

Also games are important. Xlibe and Wine make many games available, or?

More killer apps are Gimp and Blender. Both available, right?
