OK, blame me for being geeky again but I really have something to say about Gmail after using it for a couple of days.
Gmail is made with the mailing list concept in mind, so the ‘threading’ feature is really helpful to keep track of a particular thread or ‘conversation’ (Google’s term). I really love this feature, it is simply amazing.
The ‘label’ concept as a replacement of folder is quite helpful especially to handle so-called ‘cross-posting’ because with folder sometimes it is really difficult to choose where to put the message because it was posted on a couple different mailing list that probably you also subcribe to all of them.
The search features is really good. Well, Gmail is from Google, THE search engine, so what can you expect?
All of these features are already available for public.
