I have been hesitant to open article threads before because sometimes it seems like waste of a thread. If I am sure tha t people don't mind article threads, I can stick to that.
I don't know about others, but personally, I enjoy article threads the most of any other. Often the article is of interest to read and at times it generates good discussion amongst members.
I see what you mean about not wanting to open countless threads given the volume of articles out there, but I think there are lots of threads in GM that could be done away with long before ones that actually have some worthwhile material in them.
For example, currently in GM we have "Monfils the next great Spartan", "who is faster - monfils or nadal?", "Monfils future" and a couple of other Monfils threads that are not result threads. So I'm sure a couple of those could be merged, like Monfils Spartan and Monfils Future before you would have to worry about cluttering the forum with the odd article thread.
As long as the article isn't "What's next for Monfils?".
Or any other <insert player> bandwagon of the time.
