This RSS and autodl-irssi things are not for beginners, man. But when the torrents appers you are "on stage", you are there to saw, you can download that torrent. But it's important to have lot of leechers, but this leechers could be there from 4-5 mins and this counts for a smaller torrent. When you don't have good speed, good peering, you don't have chances on TL to seed back torrents to 1:1 ratio.
That's why RSS or autodl-irssi exists, to download quickly torrents with lot of leechers.
