Please restore Ping.fm integration and the dark theme to Tweetie 2.
Both of these were critical features for me, and until they return, my Tweetie 2 purchase is useless; I must continue to use the original version (which, luckily, I did not already delete).
I have personal reasons for requiring both of these features which I will explain, but a more objective argument is this: In all the public discussion leading up to the Tweetie 2 release, no mention was ever made of features being removed. Nor were the removed features mentioned on the Tweetie 2 product webpage*. Purchasers thus had no reason to expect that Tweetie 2 would be anything but an improved superset of the original Tweetie's functionality.
Had those Tweetie users who relied upon Ping.fm (or preferred the dark theme) been given this information prior to making their purchase decision, I suspect the current level of complaint would be far less. I certainly wouldn't have wasted my money by making a useless purchase. Although certainly an unintentional oversight (it's hard, from a developer's point of view, to always know which seemingly esoteric features are actually much-beloved) the result is a lot of unhappy upgraders.
Based upon a Twitter search for "ping tweetie" (and ignoring results where "ping" appears simply in a shortened URL) there are at least several hundred users who are disappointed about this omission. In my case it renders Tweetie 2 wholly useless, as I rely upon Ping.fm to broadcast my posts to readers on a wide variety of services, far more than simply Facebook or Myspace.
It is worth mentioning that I'm not upset - it's only a $2.99 loss, after all - but merely disappointed; I'm a longtime Tweetie fan (whose evangelism for the product has resulted in at least a couple dozen purchases) and I'd very much been looking forward to the elegant refinements of Tweetie 2.
Lastly, please also restore the dark theme. Much of my microblogging is done from nightclubs or at art events where a bright white cellphone screen is conspicuous and rude, even with the brightness turned all the way down. In such situations the dark theme was a godsend, allowing discreet tweeting without looking like "that guy". Or at least, looking a little less like "that guy".
Thanks for listening, and best wishes for continued success with Tweetie!
* Nor are they still, something you should probably correct.
