There are some things I have to say about the websites Hahlo and Twitstat Mobile. I tried both applications early June and both are two-way and difficult to send direct messages with. Direct messages can however be viewed. When I reply to a tweet with Hahlo, the particular tweet does not show what tweet I just replied to. In the timeline all @replies which have been written in another program have a button to show the tweet being replied to. Another annoying thing is that every few hours I have to login again. This application was built for a mobile device. Through their menu it is possible to sent a direct message to another user or even yourself.
Twitstat Mobile was built for a mobile phone too. The timeline shows multiple functions; muting users, showing a conversation between users, showing pictures from TwitPic and MobyPicture, add to favorites, retweet, and reply. There is a whole menu with settings and saved searches. This could be interesting on a mobile phone to use. The function to actually mute users you follow is similar to Twalala. The dialogue function in Twitstat Mobile does not show the conversation between users like Twalala does.
Since I last wrote about Twalala they have developed a new feature; in every @reply there is a new button in the lower right corner of the tweet with ‘Re:’ on it and when selected this shows the conversation between users. Another new feature is the link to the original tweet in a reply made with Twalala, they did not have this feature when I first used it. I tested this before and on June 20th again.
