First, welcome. =)
Show screenshots, mockups! If you take a look at
PixelJoint, you will see some people saying "I would like to play something like this!". If your game is 2D, and make use of pixelart, join this website and place your mockups there.
Once your game is finished - better, once you get the demo, release it, publish it on TigSource, send a request for the editor of
IndieGameMag, as far I know, they will play your game, if they like, they will make a post about it. Also,
IndieGames usually take games from TigSource and IndieGameMag, and make a post about them.
It is hard to get your own "slaves" with your first game, but it is possible. The screenshots are the first thing that will call attention of your public, the second is the history - by the way, never post a giant history, nobody will read a big post just about the history.
