Quite impressed by web gadu-gadu
(gadu gadu is a Polish IM)
It must be like 100 years since I saw Gadu Gadu last time. Almost all of my friends use gmail embedded chat or skype. And even before, I was rather using tlen (another Polish im).
But today I needed to contact a potential contractor who only provide GG number, and I found that I can use a web interface (web gadu gadu) instead of downloading a client (not even sure if there is one for Mac):
Looks rather cool!
(except for the flashing banners maybe)
My contact in unavailable anyway, so can’t say how well it works for now.
