Most lifestreams I saw didn’t include a way to for end users to filter out certain items, so I built one into my lifestream application. Using the power of CSS selectors built in to jQuery, I wrote a function to grab the list items with a certain class and then toggle a fade effect. If the item was hidden the script would fade them in, otherwise it would fade them out. You can see the 13 lines of code I wrote to do this for yourself.
So if you ever wanted to see everything I do on the web, checkout kingkool68.com. And if you want to add me as a friend on any of these popular sites, click the small icons associated with each item to take you directly to my profile for that site. The next step would be to package my modifications up into a WordPress plugin so anyone could run a lifestream just like mine. In the meantime if you have any problems implementing a lifestream on your own, leave a question in the comments of this post and I’ll do the best I can to help out. Happy lifestreaming!
