Pros:
1) I can access more than one IM at a time and can even log into my own meebo account.
2) It looks more modernized than the last bar.
3) The quick links are with the only links I'll ever need.
Cons:
1) The fact that it's meebo means that it'll sign on and off more constantly than a hacker on a fool's holiday.
2) The bar reminds me of an i-pod, easy to use but can not be modified for personal uses. Which while some people will enjoy, others will despise. Like for instance, "where's my stalker box? crying "
3) Ads in the corner are really troublesome, while it's understandable why they are there, if I leave my mouse their too long the screen explodes with the ad and starts playing it loudly. That can be quite a problem while profile hopping.
Overall, I'm going to deactivate it. While I love it when Gaia experiments (I have almost all of the labs activated), this was one they tried and failed. Sorry devs, you're just going to have to just make one from scratch that works as efficiently as this one.
