Has anyone ever had success on Steamtrades?

It seems like it's mostly bundle leftovers being traded and "keys" (whatever those are) and next to no legitimate trades for games with high ratings of equivalent value. People also tend to bump way too often so your post gets lost. Just curious if anyone has had success there and if you have any advice to improve visibility and getting similarly priced/rated games rather than people offering goods you aren't asking for.

ST is pretty bad IMO.  Your best bet is just to do as the rest and bump bump bump.

Make sure your title lists as many games as possible that will make people want to check your thread and lists all the games you have for trade in the posts.  Make sure you post that you don't want bundled games in return.

It will still take a while though.

Most people just have bundle crap and will offer it even when  you tell them you don't want it.  I don't know if they ever actually find people to take their trades or if they just have too much time on their hands. 

I only use it for the cards and stuff. 

Reddit is better. I get exactly what I want and keep it moving.
