If I had to guess its probably the people from india or other countries that have difficulty with the english language that are a little gunshy on skype. chatting vs PMs mean less time to construct and grammar check a reply. Are you going to hand over your bucks to someone who can barely string together a sentence? Most guys are smart enough to avoid putting themselves in a situation where you have the opportunity to make that judgement call ;-)
who gives a shit. they're both forms of communication. in the past it was ICQ primarily for adult and AIM for what the fuck ever.. now that skype has entered the convo, it seems to be AIM/SKYPE = same shit (business/chat), ICQ = for adult.
Skype. Though I tend not to do voice calls, I prefer to type so I have a log and to ensure I can explain everything correctly and not forget to mention anything.
Skype is basically the only messenger program I use now... so annoying when you want to do business with someone who doesn't use it and insists they only use AIM (lol?) or MSN (lolol).
