When a website is started for the first time, it is solicited by it to use its services in the blogs. Later when it is well established and became famous it doesn't need your usage and support anymore: it needs only revenue as it has now become commercialized. This is the matter experienced by my blogs with Wowzio: all went well with its Live Activity widgets on my blogs until one day recently, when my blogs were found without these visitors' activity widgets. They have been removed without any prior intimation, forgetting the past.
Note also this present scenario with Wowzio: for a new blog's use, a request was sent by email to it; but permission was not given and there was no response at all.
Commercialization has become the targeted plan now for all the websites. Thus it is also a factor for losing interest in blogging. Service to blogging is tapering.
