at the very least, Twitter
I am sure that Second Life will.
didn't know SL was having trouble. Seems like all the popular sites are struggling lately.
Twitter's a ghost town already!
Pownce is always sluggish.
with the Monday morning crowd doing catch-up? At least Twitter and its related API -dependant pals - also Plurk, with 'new kid' popularity
both.

Like I said, "Twitter, good customer services comes from ALWAYS under promising and over delivering!"
LETS HOPE TWITTER!!!!!!!!!!!!
Twitter goes down on days without huge announcements, so it'll be swamped. As for others, I'm not so certain.
plurk has been going down quite a bit lately, I'm convinced plurk and twitter are cousins. Or at least in bed together.
Apparently twitter is on top of it!
i have my money on twitter
Twitter, without a doubt.
It's Apple day, so: twitter
as soon as one goes down, people rush to the other and it crashes, too
ClassTax has it right. Both will spend some time in time out today.
both - Plurk is far from stable in comparison to Twitter
Twitter of course. It has problems already now, before the keynote...
Will be Pounce. But I haven't account their.
Oh, the gamble of online.
Plurk is generally stable. Both are great services, but to Plurk's credit, they have survived quite the load on way less than Twitter has.
Twitter, of course. Poor twitter.
likes twitter but he really thinks its twitter.
twitter no chance to stay without crashing.
twitter is already crippled. Great.
WWDC will kill Twitter. Wait, everything kills Twitter.
just got a "Twitter over capacity" message.
