It seems since Twitter architect Blaine Cook left the micro-blogging site has been going down nearly everyday for hours at a time.  With the emergence of FriendFeed, and growth of Pownce, can Twitter stay at the top of the micro-blogging sites?

It seems it’s only a matter of time now before Twitter gets replaced. It might have to take next year’s SXSW to claim a new king, but at this point, I’m ready.

With Twitter saying they will be recoding parts of their site in the next few months, how much more downtime are we talking? How long can the users go before jumping ship?
