We’re already three weeks into 2011. You’ve read all the trend posts (good compilation here). Seen the predictions from the digital, PR and marketing experts. But, do you know what’s really going to be hot in 2011 (insert cheesy Entertainment Tonight music!)?

My take on what’s “in” for 2011 and what’s sooooo 2010:

So 2010: Delicious (thanks a lot Yahoo)

So 2010: Firefox (my Mom uses Firefox now; it’s officially jumped the shark)
In for 2011: Chrome (lighter, faster and new app store now)

Blog platform:

So 2010: WordPress
In for 2011: Tumblr

Third-party Twitter app:

So 2010: Tweetdeck Desktop

So 2010: Disqus
In for 2011: LiveFyre (planning to install on my blog shortly)

Hot social media event:

So 2010: #fail
In for 2011: #anyoverlylongexplanatoryorironicnoteaboutyourtweet
