you dont always have to voice chat :P

ALWAYS USE CAPS AND NEVER TAKE ANYTHING SERIOUSLY

I have no friends on Steam.

Actually I take that back. I got a request from some random person earlier lol

1. Must give me game
2. Must give me game
3. Must give me game

You know that Steam has a busy chat state? You don't want people to chat with you, just let them know. :)

There was a indian guy who talk to me every second on steam i had to delete him on steam. he was annoying me too much. He always talk to me the first thing i logged on. EVEN WHEN I AM PLAYING GAMES!! the chat just keep popping up!!! had to delete him.

Well, you can say "I can't talk about this game right now" :P

I hate it when I'm online for hours, and as soon as I start a game I get like 3 chat windows.
;___; sparkle what do I do?

I don't like being bothered when playing an immersive game, and I don't bother others when they're playing a game. But if someone messages me, it only annoys me for about 2 seconds. Then the majority of the time I try to get out of having a conversation, lol.
As for the way people talk, I don't care. Being bothered is the only thing that I don't really like, but even then, it's not like it pisses me off that much.
Also, to solve your giveaway problem, here.

I usually accept anyone that send me friend requests, although sometimes when people bother me too much or I want to play without interruptions I just change my state in chat as if I weren't online.

I never interrupt someone while they're ingame, unless it's of vital importance, even if they're in a non-immersive game.

Then again, I don't have any friends...

I don't bother people when they're ingame unless i have something important to say or just want to share with them some lesbian porn (cause no one in their right mind would complain about that)

I block them if they do it after I warn them. Most have nothing to say anyways, so there's no point in chatting anyhow. Most of my older steam friends know they'll be waiting a bit for an answer if I'm in the middle of a hard game or a good part in a story or quest.

As for people who try to get your attention by spamming trade requests, voice chat requests, and group invites...I just block 'em. Not worth the time or effort with someone like that, since it's obvious they've yet to advance beyond Kindergarten levels of anything, really. :D

-never start a conversation with someone who's playing
-if no response, wait atleast 30min

I do game footage recording and I hate it when someone talks to me to ask "hey! are you recording?" Especially if it's coming from someone who knows I record the game that I am playing. Why ask me something you already know -_-. Generally I just don't talk to people who are in game. I feel like that's kinda rude or an annoyance.

If I don't know who the person is, they're not my friend - just like real life. I only have a few friends who are gamers, so I only have a few friends on Steam.

It's easy, if I don't want to get distracted in games like Bioshock, I go offline. And if I forgot about it, I'd ignore the message.

I know how you feel...

Another thing I hate about steam chat is when people start a conversation when I start up a game and they just wont shut the eff up.

Binding of Isaac don't need concentration?! Alright it doesn't really, but it's hard to keep up in group chats if you're fighting MOM at the same time ;) Anyway, I agree with you, and it's annoying when you're playing DOTA 2 aswell, atleast in the first 20min of farming. I'm trying to last hit, I can't write chat messages at the same time!

Yeah I understand. I don't like it when people do it to me (even though they do), so I don't do it to them. A simple "You won my giveaway" or "Hi" is fine. But I hate it when they are like "Hi", "Hello?", "Are you here?", "HELLO?".

I can totally understand you with that... I actually tend to ignore friends who do that, thankfully I don't have a lot like it. There was one time when I was playing BIT.TRIP RUNNER's last level before the boss, and someone started chatting me when I actually made it near the end. Then, as it is always usual, it threw me out of rhythm, and I made a fault on one of the most mundane objects, and had to restart it again. If you ever made it to that level, then you know just about how otherwordly pissed I was at that moment. But the same goes to whenever I play an online game like Half Life (1) or Killing Floor.

Other than that, I don't have anything else, really. I really freaking hate when people start to hit on me, despite the fact that it is clearly stated that I'm a male on my profile... but then sometimes it's just too much fun to mess with people like that.

I have like 25 friends usually, but they never talk to me... Should I feel sorry for myself? :P

Etiquette? I just behave normally with the other person and afford them the same courtesy I would expect from them. Many often interrupt me in game, it's very irritating. When I'm playing something like say, Skyrim it doesn't bother me too much but if it is something like Black Ops 2 I really couldn't care less about what the other person is saying. Now I just turn off chat and rarely appear online.

I do like to keep my friend's list small so I do delete people I don't talk or play with any more after a few months.

Honestly, I deny any friend request that I either wasn't aware would be coming (like someone here is giving me a code) or is associated with a giveaway. Too dang many scammers these days and I don't want to bother with them.

So honestly, barely do Steam chat, I'd treat it like any other chat though. Of course I have a bad habit of starting up a game and clicking off the window for a break and it still says I'm playing, like right now I'm supposedly playing Ys: The Oath in Felghana. Obviously, I'm taking a break from it for the moment.
