Well I think I like these things that "feed" me information all the time.
I have always liked getting email alerts from my favourite car forum website, and to me, these news feeds are a similar kind of thing. Although they are more general in nature, and a bigger variety of news comes through.
But the end result is pretty much the same: I get alerted about things that I have chosen to be alerted about.
For example, the email SMH news alerts that I get in the AM & PM are convenient ways of keeping up to date with the big news stories each day.
But I also think having too many feeds can be a bit distracting while trying to work. So I guess the key is to be selective in what one chooses to subscribe too.
