I think combining Flickr and Tumblr could be a massive win for Yahoo! They have monetised Flickr successfully and the model they use to do that combined with Tumblr's current model could see them transform revenues on both titles very quickly. I do think Tumblr should grab the offer while it's on the table, however.
Your site seems to have quite a bit of duplicate content. In fact, every search I did showed other sites when I searched for long strings of text copied from your site.
Search Google for "Whenever Jarvan III, the king of Demacia, delivers one of his rallying speeches"
Is this the most elaborate April fool of the day?
