I'm not possitive but I think that site just tried to load some malware on my windows box. Some thing call "secure service" attemped to load. Google shows the site as clean though, so I'm not sure where that just came from. My host of 4 different scanners/cleaners show I'm clear ATM.

Same here, it (MSIE8+AVGFree+Win7) locked the site for a while and moved some cr*p to a vault. The site managed to launch Adobe Reader though. Anyway I made another visit and first look is just news and links. I largely mean't NEW FORUM POSTS on any amiga site. Any Amiga site (wwmaster) plugs in (by providing the proper feed or adjusting API if no new forum feed is avaliable) and then bang, you've got the aggregator.
Instead of checking several sides all the time (several to some, only one for others), you just check all-in-one-place and then redirect yourself to the portal with some conversation you find interesting.
As far as I know it's just a matter of collecting feeds and defining them as a multiple source for some chosen cms. As I stated above, nice tree-like structure would be crucial, the original portal but also scope like hardware/software etc.
One more remark - if I myself was able to utilize such feature, I would for sure check and read EAB or some other Amiga portals in my locale. Now I don't mainly because I spend some significant amount of my spare time on Amiga sites already. Less time = more portals, at least to me.
