Last night I added a ajax tab widget in my blog. Actually I reused my code for amaderprojukti forum . Now my blog loading time is half. Hope I will release this the whole coed or will try to make widget so that every body can use it. See the screenshot bellow.
Update: 06.09.08
Just changed the js code for checking the dom ready event.
The tabs look nice. You still have some CSS codes embedded in the blog. Putting them in external file can make the pages lighter also.
