Let me save you a visit to my profile by letting you know upfront that my throwdown record is an even 0-0-0. But when I visit FanNation, the first thing I do is go to the TD section, and over the last 6 months I've read a lot of TDs. This is also my first blog, but I believe that it is an important one for newbies that enter the TD arena. These tips will hopefully spare you the wrath of the FanNation Community down the road.
If there is anything that will serve to irritate the Community, it is a TD that is started and never finished. While some FanNation members will argue that TDs are meaningless and records mean nothing, there are many members who participate that take the time to formulate their arguments and gather stats to hopefully win the debate. I would imagine that it would be very frustrating to enter a challenge and spend time writing good arguments, only to end up with forfeited turns as rebuttals. One of the reasons I personally don't participate is because I know with my job and my family that I cannot commit enough time to finish.
Which brings me to another item that will not go over well - lack of argument. If you don't have enough time when you start the TD, you will ultimately end up writing short arguments without much thought. Imagine yourself in this position - you accept a TD and spend time finding reasons why your position is better than your opponent's. Utilizing all the space available, you post your argument only to have your opponent respond with a two sentence rebuttal. I don't know about you, but that would be a huge letdown for me.
I think that these two things happen to many newbies and one of the reasons could be that too many TDs are started in one day. You won't have time to finish and you won't have time to make good arguments.
This brings me to the last topic - TD Oblivion. There are only so many active TDs that show on the main board. If you start too many in one day, it causes other TDs to fall off the board so they receive limited views and votes. Again, put yourself in the position of someone who has spent a ton of time gathering facts to debate their topic only to have no one see the TD... If all of the TDs you started have little argument and/or forfeited turns, AND they cause other well-argued TDs to fall off the board, you will not make many people happy.
My advice, should you choose to accept it from someone with no experience, is to keep your active TD number low, take the time to formulate good arguments and finish what you started.
