I visit several blogs everyday. Most of them on ...blogspot.com. Many of them do not update any rss feed, so I cannot depend on rss. I need to know when there is a new post on these blogs, in order to check their pages. Is there any mac application or even online web site service to do this monitoring for me? It is awful for me to have to open 50 tabs in browser to check each one of them. Any help on this task?
