Trouble google readers and more

Hi good morning to all,

Here a new trouble with Blogger and Google reader.

1- just see he only read the last 5 messages ????
other i know can read since 10 what's wrong or normal ?

2 if normal read only 5 messages, and you know rss update arround every 30 minuts, does it look like good to make each half an hour 5 new messages ??

3- or better to change "title" of yur blog each 30 minuts ??
in that case impossible to index for a long time pages because they change name all the time and at the end is those same messages

I think the best is to update each time rss update thrue ???

thanks to all bye for now
