Google, AIM, MSN, Yahoo, ICQ, and so on.. ICQ was the standard in my last industry, but nowadays I'm having to use programs like Trillian, Meebo, and Pidgin that combine them all since people are all over the place with chat programs.
For business I prefer not to use unencrypted ones or toys (with viruses, smileys, spammers, bloatware etc which are massively non professional) ; so no MSN, AIM, ICQ and so forth. Gtalk over SSL, Jabber over SSL, Skype (is encrypted) all using Pidgin as integrated client. The less business ones are ok if you kill all features (like Windows objects in MSN, smileys and other trype which is not interesting at all) and tell the client every 5 minutes that he shouldn't use that
Depends. Adult... ICQ Mainstream biz, most conversations, chat... Yahoo However, for some my Europe business. I use Skype.
Thanks for the replies so far guys, interesting to see Skype mentioned so frequently, I wasn't expecting that one to be so popular, but I can see how it definitely saves on phone bills.
I definitely prefer to use GTalk for my business stuff, but MSN for friends + occasionally business if they're paying well
I find that noone really uses AIM in the UK... only really if they need to chat to Americans. MSN is used by practically everyone here, YIM not so much. I have Adium as I'm on a Mac so it makes no difference to me.
Aim- I use the most Skype- trying to use this more often MSN-business only G-chat barely use but its not bad Skype is my favorite though
I actually wrote this a while back... but here it is blog about marketing/networking via Instant messengers...
Using msn messenger since forever. Lol. Sometimes I do use the built in messenger of gmail however, thats rare.
