My idea to group all the news I did not have time to comment did not work so well.
For one thing, it defeats the purpose I started this blog in the first place: to be able to assign each news to a category. For another thing, it just takes about as much time to write a single paragraph in a post as it does for grouped posts. And a third reason is that sometimes I write about something I don't think is particularly important and it turns out to be something popular (or reversely).
Thus I have now reverted to "spamming" my own blog... I try to stick to the initial purpose of this blog, which was mostly to be able to trace back news for myself, and possibly comments them along the way. That some people have gotten interested in my selection of news and my comments, and that it also has become a way of interacting with others, should not really mean I should depart from that initial purpose. I guess people can just skip whatever title they are not interested in.
Still trying to find my way through this new media...
