Minimalism in IM

My PC is slow. Why? Too many browser tabs open. I have about 70 as we speak. What to do, what to do?

My perception of what I need to keep open should change. But how?

Here is a list of 10 tabs I have open to give you an idea...

1. .liveperson.com affiliate program stats page - I view this like once every 10 days. So convenient to have it open.

2. Google dfp - check stats once every 5 days.

3. Active Collab - not using this much at the moment but worry about having the passwords so leave it open!

4. SERPassist forum - check it once every 3 days to see whats going down.

5. WordPress admin page for one of my sites. Intend to work on this in next few days so left open.

6. Found an interesting internet marketing subscription service so have left it open on that page so I don't forget it. Not sure what to do!

7. Interest Warrior forum post with manage pages I would like to read sometime. So left open on the page I am on.

8. Membership forum I use all the time so leave that open.

9. BHW forum thread, where I just ordered a service.

10. 2 hr training video ready for me to watch. If I get time.

Ok, so you get the idea. I am interested in how you would interpret the 1-10 yourself. Each is different, so how do you think about each individual one? Or are you thinking like I do and have the same problem?

Thanks,

Jon
