When you say Search by date, language and rep... are these filters that are specific to "trending" or also for "hot", "my feed", possibly "my blog" etc...
Agreed a dynamic widget word cloud that changes would be ideal. Still looking for an open source code of that that can be found... Thats a great wish list item for me 2.0 build unless i can find something to use.
Drill downs for tags would be nice. I think another great feature for 2.0 and ill add it to my feature wish list on github. thanks for the great feedback.
