A Twitter investor has hinted at charging for mobile as the future of Twitter.
Joi Ito, an investor in microblogging site Twitter, has hinted that he
sees the future of the site's profitability in charging for mobile use.
This has been added to by co-founder Biz Stone's announcement
that Twitter will not start using ads this year and that immediate
goals were to improve the search function and create a paid-for
commercial account.
