As IPO Nears, Do Twitter's Active User Claims Add Up?

netbuzz writes: With Twitter’s IPO looming, an independent developer who is intimately familiar with the makeup and behavior of the site’s users says his analysis of 1 million random accounts does not support the company’s claims of 215 million active monthly users and 100 million active daily users. In fact, Si Dawson, who until March ran Twit Cleaner, a popular app used to weed deadwood and spammers from Twitter accounts, puts those numbers at 112 million and 48 million, respectively, or about half of what Twitter claims.
