While reading or using other's solution we should upvote his/her solution if we are able to understand or if we are convinced with his/her solution. xD (I know it sounds boring)

I had this tendency of not giving upvote even if i really enjoyed the solution of other person but it really feels good when someone upvote your solution or just thank you for your solution. I am not saying to upvote every solution you read but atleast upvote the solution which you think it helped you a lot or you like the way of implementation or explaination.

This suggestion of mine may not work for readers but discuss portal writers will understand what i want to convey. :-}

Still just a general and healthy suggestion so completely your choice. :)
