Un-closed old threads (answered)

Question

There are n number of old threads which has been answered but not closed by poster or our admin panel. I am not clear about the answers (whether they are to the point or not), but personally think no use of answering a thread/question which was raised before a year.(like: http://www.c-sharpcorner.com/Forums/Thread/75284/loading-multiple-tables-in-a-datagrid.aspx or http://www.c-sharpcorner.com/Forums/Thread/104306/client-side-data-lose-when-posback-occurs-in-Asp-Net-C-Sharp.aspx etc.). No one will be waiting since so long...
