@Chump Thumper
thankyou for the good discussion.
Its a fine line between having your items manageable, and in a format that promotes selling, while not being flat out annoying.
Now, i posted a bunch of stuff today that ive been putting off for a while, but did have a reason for the seperate posts
More people than you would think (apparently flutter included) only read the thread title. if its a "list" many dont bother to check to see if somethings new has been added. This is especially true for very casual browsing via a phone. (also people tend not to scroll way way down on a phone)
For example: Olcher had the same item for about half the price on multiple occassions listed for over half a year, but when the same item popped up with the actual name in title, those sold. the last time this happened it was phoenix tickets. 2 actually sold for double the price of olchers which had been buried in a list for half a year.
So thats one issue.
The other issue is "New" items usually do better in their own thread. However, even then when i have many "New" items for sale, ive listed them all in one thread while just updating the title with maybe the 3 latest items. Couple months ago i had enough for sale that i thought it best to divide it into "old" items and "new" items. I generally find that once a thread gets over 10 - 15 items it can be overwhelming. Take Olcher, one of the largest rares sellers with over 200 items currently for sale, thats a list that can just be out of control and items easily overlooked by buyers.
Also some items i feel a seperate post is warranted just because of how good the item is (plus when the name is in the title, those posts show up first on stratics search and "similar threads" rather than the sub-results taken from the interior of the post.
Finally, as you said, if there could be bidding this can also influence an item getting its own thread. The 3 items i posted in 24hr auction format i decided warranted their own threads because of the diversity of the items (halloween, oldschool, bugged) if they were similar items i would have put them all in the same one.
Now, we do all like to have the first item on the page. lets be honest, having your item appear first can sometimes mean the difference between a sale, or it sitting in a thread for months. Everyone does at times sorta bump there thread if it gets buried way to quick (like if it was a heavy drop night) but excessive bumping, or bumping less than 24 hours is usually not too much of an issue in most cases. Pet peeve of mine is when the mods inform someone bumping a post when its been less than 24 hours in the actual thread, which again gives them a free bump in an already overly bumped thread for the day.
On a final note, i do try to avoid needless "bumping" in the form of "thankyou" bumps by instead giving a simple "like" if the seller chooses to give positive feedback after a sale. its especially considerate of a seller imo if its say an auction with 100 items. you dont need a "thankyou" bump for each seller involved in the auction. just my personal preference.
Anyway, just my reasoning. feel free to disagree. oh and in the trade forums, every so often i just go back a few pages and bump the stuff thats still active. i suppose i could put that all in one thread, or 2 seperate "buying" and "selling" but yeah i just bump them all out of pure laziness. if its gets to be to many ill try to condense when i have time.
