Great to see that Google Talk is adding improvements. I just noticed this one, for example: Drag a photo into a chat window and it appears in the chat itself. Click on the picture and a little progress bar lights up on the right as the recipient accepts the picture.
Resize the window and the picture resizes:
This is good stuff, especially when you compare it with Skype, which for some reason no longer allows dragging of files or links into a chat.
Chat, in short, needs to fit the conversation. And conversation involves sharing things, looking at things together, and generally connecting to each other.
Switch to Google Talk. Skype, get your act together.
