Reminder Bear is an application that you can use for remembering to check sites that you came across once, and that seemed to hold some potential. Well, by signing up for this service you will get a reminder to check these sites out at a specific periodicity.
Additionally, Reminder Bear can be used to follow comment threads that you saw and liked, but that you did not contribute to. Normally, that scenario would mean you would not be getting updates whenever new threads are added. But Reminder Bear changes that, and enables you to remain fully abreast of what is being said on that comment thread.
As a service, Reminder Bear is free to use. You can keep a watch on as many sites as you want, and do so without having to pay a single thing for the privilege. And there is no need to sign up for the service – you simply use your email address in order to begin receiving updates.
