-A) Did you know about the giveaway listing thread previously?
-B) Will you begin/continue to use the thread. If yes, why? If no, why?
No. I most often consider that the giveaway's method (riddle, contest, technique of randomization, general theme) is more interesting than the giveawayism itself. I even like giveaway threads that are not labelled [giveaway]. The giveaway thread feels like being for people who are specifically on the hunt for free, given games. Giveaways and participations feel more spontaneous to me when indivudual and chaotic, even unexpected.
-C) Do you think the name of the thread should be changed so that its purpose of advertising giveaways is more obvious? If yes, why? If no, why?
Yes. Right now it doesn't completely serve its purpose. It advertises the giveaways to people who "know where too look" exclusively. The irony is that giveaway threads serve as advertisements for that one...
-D) Or do you think a separate thread is more convenient for "giveaway advertising" leaving the former to its original purpose as a FAQ on gifting? If yes, why? If no, why?
I think so. Not only the current title conceals the thread purpose (people won't click on "howto" to get a list of giveaways), but it kinda works both ways : when you click on that htread and get to the last of a series of pages of announcements, you may just think it is the wrong place to get info on gifting procedures (even if you'd find some if manually navigating back to the OP).
-E) Suggest the thread's new name, if you think the change is necessary:
Hm. "Good Old Giveaways", or "Generously Offered Games", or "Gamers' ongoing Generosity"... (Or "Gome ond Getem".)
Or "Shrine of Altruism", if it's for records and archives more than annpouncements. And yes, i AM pompous.
-F) Any suggestions / constructive criticism to improve it?
Not really. As I said, I don't think it's a very necessary thread, or one I'd use. I find that it formalises the giveaways a bit too much, making them feel subtly less chaotic and random. But if it has to exist, then being a separate thread with a specific title would indeed benefit it most. Maybe even being a sticky.
I have more fondness for the "gaming sales" thread (because it's good to know what's happening elsewhere, also the matter there is more strictly commercial so the spreadsheet effect bothers me less), for the exchanges threads (that may also benefit from a clearer title than "classifieds") and for the community gifting thread (that should make absolutely sure that people's wishlists are kept uptodate - having the recieved games still listed but crossed out would be perfect, if the forum allows or allowed it). At some point I wondered if the giveaways thread should be merged with the gifting thread, but it would make it more difficult to read. Also, if not stickied, maybe having something special in the title, reserved for such institutionnal threads. Like a liberal use of capital letters, or maybe brackets or asterisks around the title. Something that makes these threads stand apart as semi-official. Ideally, if the moderator and forum engines allow it, having the title in a different colour than the other threads.
But as for the content itself, I think it's okay as it is : keeping the announcements as one minimal sentence with a link.
