I honestly don’t give a shit about Tumblr blogs that are like 95% reblogs, which most blogs on Tumblr are. I end up giving up trying to follow what people post because there are just way too many damn posts; on a typical blog, one page (if any) is equal to about five minutes. I’d rather see media and text that was created by the blog author themselves; one’s own words and creations, if you will.
There is also the various problems that come up if I send the person an ask message; I will most likely have to nag the person to respond privately so I get a notification that my message was responded to. No such convenience provided for a publicly-posted response; I have to pray that the person tagged me and check manually, or dive into tens if not hundreds of pages of posts to find the response if they didn’t tag me, especially if I sent the message a few days ago; every day I forget to check is 250 more posts to shuffle through. Sometimes I may go through this effort only to find out the person did not respond at all.
Plus, I’m a stickler for organzing things (maybe to the point of mental disorder), and reblogging en masse is anathema to organization because I have to stop and apply necessary tags, lest everything gets lost in an unsearchable mess.
That’s why I don’t post much, why I rarely reblog material unless I have more than tags to add to it, and why I generally don’t follow blogs by even people I’m close or best friends with unless they pursue the same “use Tumblr as a personal blog” philosophy.
