Any threads in particular you’re referring to?
Some people just like to lurk and educate themselves, so they read stuff without chiming in. Participation would be great, but there’s nothing wrong with just cruising around.
Other times, a thread’s question might be too complicated, too poorly worded, or just too confusing for people to offer advice on, so people give it a read and then bail. Nothing wrong with that either.
Also, the thread views include daily visits from members and non-members, so if someone stumbles their way into any given thread, it’ll count their visit as a view whether or not they have the ability to comment. Or if someone posts a comment, then comes back the next day to check for replies, it’ll count as an additional view.
Or… if you’re only here to talk anabolics and never keep a training log to share your workouts and diet, why be here? (See how weird it sounds applying arbitrary expectations to people?)
