A "discussion" forum?
As opposed to, maybe, a non-discussion forum? What else do you do in forums?
A clue: whenever you see "foos, bars, and other bazzes" in a description, you KNOW you can just remove "foos, bars, and other", and the sentence will still mean exactly the same thing.
The same rule applies when you see "all kinds of bazzes, including foos and bars". Just cross out "all kinds of", and "including foos and bars".
If the site included NO kinds of bazzes EXCEPT foos and bars, we'd just say "including foos and bars." If the site included "foos, bars, bazzes, and bins", we'd probably look for a generic term for all of them, and just say that.
Any absolute phrases get whacked right off. And "all kinds of" is one of those phrases that stands up and says, "hyposuction squad needed in aisle ten."
But that's all pretty straightforward, and close to describing content on the site. Enough, at any rate, to begin looking at the site.
Now we'd look for UNIQUE content: are those programs already available elsewhere? If so, is this site the official source? If not, then it's not unique content, it's just clutter. Is the forum really on a unique subject? Is is really active, or would surfers be better served to not see this site, and instead be directed to a more active or authoritative interactive site? Is the news copied? if not, is it really substantive, and is there a track record to show that some sustained reporting process is firmly in place?
Any part of the site's content could fail the sanity check: we'd whack it out of the description, and go on to check the other parts. But after three or four parts, if there were nothing, we might well just dump the site altogether -- our job is to help surfers find content, not send them on a scavenger hunt through a morass of recycled bits. We wouldn't so much use the suggested description as take it for a guide when looking through the site for content.
So if you have a mixture of original and plagiarized content, you can help the site by featuring the original content prominently in the description, and saving the non-unique stuff for the back pages. We don't mind non-unique stuff -- most of us have posted some ourselves -- but what gets a site a listing in the ODP is actual value, not mirror images thereof.
