I would like to clear on the homepage all the items I've already read.

I had twitter in mind, when I was writing this. Tweetdeck has this feature, where you can "clear" the column and it just drops all it's content, and only new content from that point appears.

At the time I was trying your tool, I had all the items from the OPML and twitter I've imported already read, you cannot just mark all the iteams as read.

There is no way to distinquish what I've read and what not. I expect the reader to remember what I've read and not bother me with them again. I don't wanna read anything twice and think "have I ready this? where have I ended" ... to solve this is exactly the reason I use readers, but your social integration is not doing it for me. Or have I overlooked something? The twitter is just reading.. I want it to remember where I've been last time and pick up from there.

Okay, thanks for clarifying that for me. Social items are not bolded the way RSS items are in the Home tab and there's no way to filter or remove them after you've viewed them. So, I can see how it would be difficult to figure out where you left off reading. 

I think it's a great idea to either clear all the items or at least, add a filter like the one you mentioned in your other post. I'm going to pass on all your points for discussion and will do my best to keep you posted about what they decide. 

Thanks again!
