Well worth a look
The Wolfson talmud has changed completely over the last few months, unrecognizable to before. The only drawback is that each tractate costs just under ten dollars, whereas most similar content on the web is free. But it has a lot of advantages. As before, you can see the block of text being discussed, but now the UI is not cluttered and is very fluid. The shiurim are concise, and it's very easy to play back a section, and to adjust the speed to exactly what you want. The dictionary is amazing. Click on any word and it gives you the translation. Don't know if there is anything like it, obviously a lot of work has gone into this. Only wish the shiurim cost less or that there was a package deal.
