Aggregating relevant news in Web 2.0
I was reading through my aggregator this morning and came across some postings that didn't really have anything to do with things that I subscribe to. This didn't bother me as I find some of the most interesting things through these types of posts, but I did wonder where they came from. I looked at the source and it was the Macromedia aggregator. This particular news feed is one of those I am aggregating from a source that is already an aggregation. My first split-second thought was that these things shouldn't be up there since they are not macromedia or web-development related, but then I considered my own blog. I have no idea in what contexts it may be getting aggregated. When I post off topic, it is still on-topic in the realm of my blog and feed as it concerns me somehow, but if for example my blog where aggregated with other web developers, many of my postings would be very off-topic in that realm and I wouldn't even know it. As a micro-content provider, one never knows how your content is being grouped elsewhere on the web.
Is this just going to be a characteristic of the new web or will the idea of tagging and categorizing micro-content become increasingly important? Is it the responsibility of a content provider or the one who aggregates to get clean relevant information?
