Before I start let my say that I am aware that there are more types of exploits (i.e. R-JTAG) that accomplish the same things but in different ways. That being said, there will be no confusion.

I get very annoyed with people who buy a JTAG or other modded console when they know nothing about them. To add to that, I also get annoyed when people decide to buy a modded console when all they intend to do is host modded lobbies. Most of these people have no idea how to host modded lobbies with a modded console meaning: they don't know the methods to go online, the risk of system link hosting/recoveries on a retail, the use of tools through SDK and how to switch mod menus (.dll's), ect. Do these people realize the amount of things one can do with these consoles? Use them to their full potential instead of just hosting modded lobbies. For example: downloading game files or GOD to HDD for free or unlocking XBLA games. You can also modify the games and get free DLC if you use game files. I also love playing on LiNK which I know many people know about, but never set up. I even found a tutorial months ago on emulators and how you can play N64, PS1, and original Xbox games. These are just some simple examples.

Bottom line: Do your research before buying a product. If you are going to buy a JTAG/RGH, Youtube, TTG and Google are your friends.
