I found this article a little hard to follow. I think the author is making the general point that we need more active developers (agreed) and the more specific one that we should resurrect browser projects like Phoenix and Oregano (not agreed).
Put simply, NetSurf is working and is producing results - let's get behind that. There are many other areas that RISC OS programmers could get involved in: ROOL work (especially the essential filesystem project, the PostScript printer driver work, or a new CDFS), a media or Flash player (there is already a Gnash port needing finishing off), or development of core apps like PhotoDesk. What we don't need is a browser war.
