I use rss reader - fireant- on windoze to get the photoshoptv video blogs. It works quite well, but like a number of programs it tries to take over your world. I also found and downloaded some old films, and it handled that nicely in the background.
On one of my sites, I use an rss feed, and asked 'customers' to install a reader. I only send out text site update links, infrequently now, but it does not work too well, seems to repeat messages randomly, I am uncertain if its a server or reader issue. (can't think its my xml coding ;-)
I contacted fireant, but I could not switch to them for reader, they needed video content.
I sort of got into rss feeds via the bbc.co.uk site, and was interested in some of the news topics, but it came down too fast, and took a lot of manual filtering, so I unhooked from them.
I think rss is a very good idea, but only if it is linked to specific areas of interest. I guess its something like paying direct debit - you set it up and forget it, but the provider is still in some sort of control.
I am not sure if it would be useful here, in any active forum situation, I think it works best, for me, if its a regular broadcast, to save logging in every week/whenever.
Best wishes,
Ray
