Maybe the ordering of the default tab should be more sophisticated, both for new and logged-in users. The "Activity" tab would then not be the default one, and the default one could e.g. be called "Interesting". It would be ordered by an interest score that should take into account both last activity and votes. For logged-in users, questions they personally were involved in (asked it, answered it, commented on it) should get an interest boost (as you are more interested in posts you engaged with).- An example ranking algorithm could be as follows (note that I didn't give it too much thought, so that should not be taken as proposal, but more as a starting point; also note that it would have to be adapted for non-question posts).
- For each question, we consider the following numbers:
- * The Wilson score *w<sub>q</sub>* of the question itself.
- * The Wilson score *w<sub>a</sub>* of the highest scored answer. If there is no answer, *w<sub>a</sub>*=0.
- * The number *n* of other questions that got activity after the last activity of the question.
- * An adjustable positive constant *A* (which basically determines the weight of the last activity)
- * An “own post” factor *o* that is 1 for posts the logged-in user was not involved in, and an adjustable value greater than 1 for posts the logged-in user was involved in. For non-logged-in users it is always 1.
- The interest score could then be calculated as
- > score = *o* × (max(*w<sub>q</sub>*, *w<sub>a</sub>*) / (*n* + *A*)
- That way, questions with higher score or higher scored answers would rise, but questions whose activity is longer away would get less weight. The older the activity is, the less the time would matter.
