You may be able to get away with scraping a portion of the site, but I still would find it very hard to believe you'd be able to scrape even 50%. Let's do some math, these are all based on numbers from this past June which have likely only gone up since then [1]: 65 million tweets per day / 20 tweets per page = 3.25 million page views per day Just to keep up with the stream, you'd need to do about 3.25 million page views per day or a little over 1.5 million to get half of it. Again, I'd find it very hard to believe that nobody at Twitter would catch on.
