A friend sent me a link to a page with the Twitter Stats.
Wow, 3.5 million tweets per week, not counting locked and direct tweets. That’s about 350 tweets PER MINUTE (rules of thumb: ~10K minutes in a week; ~PI*10^7 seconds in a year).

Even Exchange can handle that.
The data feed produced by the Options Price Reporting Authority contains every transaction on every stock and option exchange around the world. The current projections for OPRA are here, but let me republish the table for you:
Yes, that’s 701,000 messages PER SECOND, or about 423 BILLION messages per week.
Where’s the bottleneck again?
