- I Love IM
- MSN webmessenger
Through my own experience so fast the worst one i reckon is the web messenger by MSN itself. MSN used to be able to signin on it's own but don't know since when they changed it to login via the email side, it is confusing and not user friendly at all
The rest of the above mentioned providers are not bad but the loading time is the main issue. Ebuddy is the most regular one that i use but the ads is the most annoying one especially i use it on my mobile HTC HD2.
I just discovered imo.im it loads very fast, even though it doesn't support the extended emotions but for only sending instant messages i find it very good and very clear cut, it doesn't bug you with the annoying ads like what ebuddy does.
I highly recommend imo.im as an alternative for your web instant messenger if fast loading is your major concern.
