I don't personally feel that Yahoo! has ever done anything by halves, it's either "all or nothing" and in the case of their new Yahoo! Messenger for the Web they have without doubt, dished up an "all".. with a little room for improvement, but more on that later :)
What Can't you do?
Conference or Chat, File Transfer, Photo Sharing, Voice or Video, use IMvironments, Audibles, LaunchCast Radio, PlugIns and Audibles.
One feature I missed terribly, even though it's not even available in the Yahoo! Messenger desktop client, is a spell checker, I guess I'm just use to having one available in the majority of my browsers when needed, there is one available in Yahoo! Answers (not so good), Yahoo! Mail Beta (which is brilliant!) but alas not in Yahoo! Messenger for Web.
What else can't you do?
umm... I really don't think you can go past the new Yahoo! Smileys :p
the bee :D
but there is a pirate also..
but it's not as cool as the bee ;)
If I used Yahoo! Mail more often I might find that the size of the adverts displayed in there would rattle my chains eventually, but there is a premium service available which I believe removes them so it would be a "put up or shut up" clear cut situation. I don't do Yahoo! Chat so I have no idea how intrusive those ads are, but I understand from others that they are one of the worst...
Why is there a big advertisement in Yahoo! Messenger for the Web? Yahoo! Messenger free! But not for us. For us, providing the best, most feature-rich (and fun!) messaging environments available anywhere costs money. We want to keep offering Yahoo! Messenger for free, and we also want to invest in even more and better features in the future. So we decided to show an ad.
Working with Messenger users, we received feedback that the most unobtrusive place to put an ad in Yahoo! Messenger for the Web is at the right side of the screen. So that's where we put it. It won't expand, and it won't turn into a school of fish swimming across your screen.
"Coming Soon! Yahoo! Messenger for the Web is not yet available for your country"
then don't worry, as there seems to be a very simple way around this that works a treat :)
My main Yahoo! ID is bourbon_bee, it's associated with firstname.lastname@example.org (due to my being based in NZ) and every time I tried to login to the web messenger I was automatically redirected to a Yahoo! UK web messenger page displaying "Coming Soon" notice, if I switched ID's (to a USA based one) I was in with a grin, the limit is understandable but still frustrating if you're are one of the many users stuck in the endless loop. I was quite prepared to accept this and just wait it out... that is until I checked out Sarah's Yahoo! Messenger web release blog post and noticed one of the comments by "user" which indicated that all I had to do was change my Preferred Content setting.. so I did.. and tada! instant access to the web version.
