Unless the authors announce it, no, you won't know if anyone else is writing a guide. But don't worry about it if they are. Your goal is to write a great guide, not the first guide. Even if you post yours second, if yours is better, yours will be stuck.
Two tips to help you start off with writing guides:
1. Try to find a small PSN game or two to start off with. It's usually easier to write a guide for 12 trophies than it is for 40-50. And in the event that you do have competition, it's probably less time you put in to write it than you would have for a guide 3-4 times larger, so that should help it sting a bit less.
2. Listen to feedback from other members using your guide. If they offer alternate suggestions for getting a trophy, check them out yourself (you can play the game fresh by creating a new user on your PS3, and then earn all the trophies again to test. great way to verify any suggested strategies) and if they work, add them to the guide and give them credit for it. And if anyone offers constructive criticism, take the time to read over it and listen to it if possible. Basically, the end-game here is that you should never be one of those people who responds to suggestions or feedback with "if you don't like my guide, feel free to write your own". Those people come off as terrible guide authors (to me anyway), and more importantly, you never know when someone you tell that to will take you up on that offer and end up creating a better guide that gets stickied over yours.
That's my 2 cents on it anyway. Good luck!
