Yes some sites are updated all the time, news and press media for example can be indexed within minutes of publishing. Google measures many factors like what type of site it is, link quality and quantity, content, bounce rate, amount of time spent on site, click through rate, etc. etc. which can shift indexing around. If I were running a search engine I would want to produce the most up to date, relevant quality content.
